Face recognition

Face recognition Face recognition are processes involved in recognition of faces. Explanations of face recognition include feature analysis versus holistic forms. Remembering and recognising faces are an important skill one applies each day of their lives. It is important to the social interactions, to work and school activities, and in peoples personal family lives. Although most of the research in this area has been undertaken on faces it is in fact rare in real life that we need to identify someone from their face alone. Information from a persons clothes, voice, mannerisms etc, and the context in which we encounter them all help in the identification process Sometimes we fail to recognise someone because they are not wearing the clothes we normally see them in or because they are in an unexpected context. Holistic form theory is an unconventional to feature analysis approach to face recognition. Although features are important in describing faces and therefore do have some role to play in face recognition, dependence only on bottom up processing for such a complex activity is very unlikely. Bruce and Young (1986) proposed a top down approach to face recognition in which they argued that recognising a face is a highly complex process involving stored knowledge of semantic and emotional information and is therefore much more than adding together the sum total of a faces features. According to the Holistic approach a face is recognised as a whole, analysing not just the separate features but also the configuration of the face, the relationship between the individual features, feelings aroused by the face and semantic information about the face. Such an approach is sometimes referred to as a template model (Ellis 1975) whereby we have a stored template or pattern for each person as we k now and when presented with a face try to match this stimulus to our mental template. Several studies illustrate how recognition depends on the layout or configuration of the face as a whole. Young and Hay (1986) demonstrated the importance of configurable processing of faces. They cut pictures of famous faces horizontally and ensured the participants could recognise the two separate halves. Then they combined two separate halves together and measured time taken to and accuracy of, naming the top and bottom halves of the composite figures. This proved very difficult for participants as the composite seemed to produce a new holistic face in which it was difficult to perceive the separate halves. A particularly intriguing find was that if the composite faces were inverted participants could name the to half much better than when the faces were the correct way up, despite the fact that inverted faces are normally much harder to recognise. Similar research involves disrupting the configuration of the faces in other ways, either by scrambling the facial features or by inverting the face. Haig (1984) showed how recognition times increased for faces of famous people where the spacing between features or the configuration of features had been altered. Yin (1969) found that inverted faces are much harder to recognise. Although errors are found when attempting to recognise any object that has been inverted, faces seem to produce particular difficulties. Cohen (1989) suggests that this demonstrates that faces are normally recognised holistically, and inversion destroys the global pattern relationships between features. Thus, such findings could be interpreted as evidence for the holistic approach to face recognition.Mohammad A consensus has developed that the process underlying face identification (meaning the process by which a person recognizes a visual stimulus as being Aunt Bertha, my mail carrier, or Arnold Schwarzenegger) and the process underlying most forms of basic-level object recognition (Meaning the process by which a person recognizes a visual stimulus as being a table, a boat, or a human face) are different. A number of lines of evidence showing dissociations between face identification and basic-level object recognition support this conclusion. For example, faces are more difficult to identify in photographic negatives than are basic-level objects (Bruce Langton, 1994; Galper, 1970; Galper Hochberg, 1971; Phillips, 1972), and faces show greater recognition costs when turned upside down than do basic-level objects (Carey Diamond, 1977;Scapinello Yarmey, 1970; Yin, 1969; see Valentine, 1988, for a review). Additional evidence that face identification and basic level object recognition are accomplished by different processes comes from work in neuroscience. Sergent, Ohta, and MacDonald (1992), using positron emission tomography (PET), found regions of the right hemisphere that become active during face identification that are not active during basic-level object recognition. Further, a righthemisphere advantage for identifying faces is well documented (for reviews, see Davidoff, 1982; H. D. Ellis, 1983), whereas the evidence for hemispheric specialization during basic-level object recognition is far less clear, with some studies finding a left-hemisphere advantage (Bryden Rainey, 1963; McKeever Jackson, 1979; Wyke Ettlinger, 1961; Young, Bion, Ellis, 1980), others finding aright-hemisphere advantage (Schmuller Goodman, 1980), and still others finding no advantage for one hemisphere over the other (Biederman Cooper, 1991; Kimura Durnford, 1974; Levine Banich, 1982). Perhaps the most persuasive evidence that basic-level object recognition and face identification are accomplished by different processes comes from studies of brain-damaged patients showing a neurological double dissociation between the two processes. Farah (1994) found 27 cases in the literature in which patient showed impaired face identification but intact basiclevel object recognition and 16 cases in which a patient showed impaired basic-level object recognition but intact face identification, arguing strongly that different neural subtract underline with two tasks Given that face identification and basic-level object recognition occur through different processes, the next logical question to consider is how the memory representations used for the two processes might differ. The most common speculation in the current literature is that faces use configured or holistic representations, whereas basic-level objects use featural representations. Unfortunately, this method of characterizing the differences in the representations is rather vague, and as OToole, Abdi, Deffenbacher, and Valentin (1995) and Bruce and Humphreys (1994) pointed out, it has different meanings for different researchers. When researchers say that face identification uses Further support for a holistic model of face recognition comes from studies investigating the superiority of recognition over recall. People have been found to be consistently better at recognising faces seen before than they are at recalling them. A study by Ellis et al (1975) illustrates the difficulties involved in recalling faces. Participants were shown six photographs of male faces for ten seconds and then asked them immediately to recall the face so that it could be reconstructed using photo fit materials. When judges attempted to pick out the target face from the photo fit reconstructions only an average of 12.5% identifications were correct indicating that the reconstructed faces did not closely resemble the original stimulus face. It seems that in order to describe a face we need to convert our stored mental representations of that face into words. The fact that this seems to be so difficult and so ineffective as illustrated in this study would indicate that we do store faces as wholes rather than as sets of separate features. According to Bruce and Youngs Holistic model of face recognition there are different types of information that can be obtained from faces, some of which are used for familiar faces and others for unfamiliar faces. When firstly we see a face it is encoded structurally, meaning that we encode the visual information, processing the look of the face. If this matches an existing face recognition unit (FRU) then this will be activated. The FRU contains not just physical information but also semantic knowledge. Activation of the FRU triggers activation of the person identity node which enables access to a wealth of information about the person including their occupation, interests, where we normally encounter them, whether we are comfortable with them or not, whether we have friends in common or not. The final stage in the recognition process allows for name generation. According to Bruce and Young names are stored separately to the FRU and person identity nodes but can only be accessed via the identity nodes. This would explain the frustrating and embarrassing experience of knowing lots of details about a person we meet but not being able to think of their name. Young, Hay and Ellis tested the Holistic model in 1985. They asked participants to keep a diary and record problems experienced in face recognition every day. Out of 1008 incidents there were no reports of naming an individual without knowing other information about them. But in 190 cases the opposite occurred, participants reported knowing information about individuals but could not name them. These findings are consistent with the sequence of events proposed by the holistic model where by names can only be accessed if semantic information been accessed first. Further analysis of the diary data showed that of the 1008 incidents there were 233 reports of experiencing familiarity without any personal information being available. Again this supports the sequential nature of the model as these would be cases where an FRU has been triggered causing the feeling of familiarity, but the identity Node has failed to activate, hence the lack of availability of any further information about the person. Holistic form theory is an alternative to feature analysis approach to face recognition. Although features are important in describing faces and therefore do have some role to play in face recognition, reliance only on bottom up processing for such a complex activity is very unlikely. According to the Holistic approach a face is recognised as a whole, analysing not just the separate features but also the configuration of the face, the relationship between the individual features, feelings aroused by the face and semantic information about the face. There is also another theory called feature analysis theory which is an example of a bottom up theory in which it is suggested that analysis if individual facial features plays a crucial role in face recognition.

Accounting Essay -- essays research papers

Revenue Recognition Policies The purpose of this paper is to compare the revenue recognition policies of two companies in the search, detection, navigation, guidance, and aeronautical systems industry. The two companies I have selected are Aerosonic Corporation, and Esco Electronics Company. Esco Electronics Company is engaged in the design, manufacture, sale and support of engineered products. These products are used principally in filteration/fluid flow applications, electromagnetic compatibility (EMC) testing, and electric utility communications and control systems. The filtration/fluid flow and EMC testing products are supplied to a broad base of industrial and commercial customers worldwide. At the present time, electric utility communications systems are marketed primarily to customers in North America. The four primary industry segments of Esco are Filtration/Fluid Flow, Test, Communications, and other. In order for Esco to conform with generally accepted accounting principles, management must make careful estimates in preparing the financial statements. These estimates are for anticipated contract costs and revenues earned during the life of the contract. These amounts affect the reported amounts of assets and liabilities on the company’s financial statements. Actual results could differ from these numbers. Revenues are recognized on commercial sales when products are shipped or when services are performed. Revenue on production contracts are recorded when specific contract terms are fulfilled. These amounts are determined either by the units of production or delivery methods. Revenues from cost reimbursement contracts are recorded as costs are incurred, plus fees earned. Revenue under long-term contracts in which the previous two methods are inappropriate, the percentage-of-completion method is used. Revenue under engineering contracts are generally recognized as certain â€Å"milestones† are attained. The percentage-of-completion method recognizes a portion of the estimated gross profit for each period based on progress to date. Progress to date is based on three factors. These three factors are the costs incurred to date, the most recent estimate of the project’s total cost, and the most recent gross profit percentage. Progress to date is assumed to ... ...s these items as sales. Like Esco, Aerosonic follows the percentage-of completion method to account for long-term engineering contracts. Revisions in costs and revenue estimates are reflected in the periods in which the revisions are made. Provisions for estimated losses are determined without regard to the percentage-of-completion. Like Esco, Aerosonic’s financial statements are based heavily on management’s estimates. To auditors, this raises a red flag. Auditors must be careful when conducting the audits of these particular companies. It is rather easy, and conceivable for management to manipulate earnings to meet projected totals. Another important area is that a company like Aerosonic has one major customer, and that is U.S. government. Another important factor is that Aerosonic recognizes revenue when title transfers to the government. Since the two parties are closely related in a business sense, Aerosonic may have the incentive to push titles of products to the government to meet target revenues. Auditors should take care in determining whether or not the financial statements conform generally accepted accounting principles.

Biblical Worldview Essay

Biblical worldview which can also be Christian worldview refers to the framework of ideas and beliefs through which a Christian individual, group or culture interprets the world and interacts with it. It is how one perceives the world through their Christian view. The world view impact the choices one may make throughout life and is based on our principles and ideas. Leadership for transformation: The impact of a Christian worldview states that â€Å"But worldviews are also ways of life, for beliefs direct us, values guide us, and principles motivate us to certain kinds of action and behavior.† There are many things in life that helps us shape our worldview in today’s society. Romans chapters 1-8 gives us vital information regarding identity, relationships, culture, and about the natural world. Natural world was created by God through his words. I believe and feel in my heart that God is the creator of heaven and earth and all things that exist. The article states that God is Creator, unseen but not without witness, beyond comprehension but not unknowable, powerful but not impersonal, and freedom granting but not controlling. In Romans 1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse. God created day and night, he is responsible for the sun that shines in the day and the moon that is bight at night. He created men and women in the image of his likeness and with a purpose and plan. He created us so that we can form an intimate relationship with him. I also, believe that God created us in the natural world as sinners, and his son Jesus Christ was sent here to save us from our sins. Human Identity is based on our relationship that we form with God. Jeremiah 1:5 – Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations. From the day that we were created it was for Gods purpose and plan for our lives. Once you accept Christ into your life you can then began to see your identity, it is based on our calling from the Lord. With Christ in your life you will see life in a whole different perspective. In Romans it talks about how our identity is rooted deeply in our commitment to God. For as many as are led by the Spirit of God, they are the sons of God† (Romans 8:14, KJV). So with that being said our identity is based on our relationship we have with God, not by our environment or surroundings. Romans teaches us  about how we should treat our human relationships. Sometimes human relationships are the most difficult and hardest to keep in order. In Romans the first chapter 29th verse. It explains how we are filled with unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, deceit, malignity; whispers. Romans shows us that we are all full of sin and we must turn to God and have a relationship with him, before we can have form human relationships. When you have a relationship with God you can learn how to treat others and respect others. Romans 12:10 Be kindly affectionate one to another with brotherly love; in honour preferring one another. When you help and be a blessing to others, God will bless you abundantly. When we are unfaithful to God we run the risk of affecting our human relationships. Being that we were created in God’s image it is only right that we love each other as God loves us. According to John Valk article all humans are to be treated with dignity and respect regardless of their situation or station in life. Romans also had messages containing culture in its scriptures. Romans 1:16 For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. God is not a God of color, or culture it is for anyone who believes in God and follow his commandments. D. Kim article states that we assume that morality is culturally relative, that ideas and beliefs emerge historically by cultural forces, and are not right or wrong in any final sense. Different cultures have different beliefs, but in Romans it speaks of only believing in the word of God. Romans tells us the God does not save according to cultures, he saves by people believing and having faith. So, now after the knowledge I received from reading Romans is that I have to trust and believe in God, no matter what culture I’m from. In conclusion after we have learned that Romans Is immense and detailed. It gives us information for our salvation. That nothing in our lives or without God or by accident. It teaches us that we must believe in God to know and understand or identity, to form our human relationships, and understand that culture does not exist when you believe in God. I am so glad that God saw fit to send his only begotten so that we can be saved from our sins. BIBLIOGRAPHY Kim, David. & McCalman, David. (2012).

The Roots to Happiness - 907 Words

The Roots to Happiness Whether you are down to your last dime, bumming around in your worn down denim, or parading around town in your Bugatti Veyron; your attitude towards life is what you make it to be. With an optimistic outlook, you can obtain happiness in any given situation that life deals you. Do you know how to be happy? Or are you patiently waiting for happiness to find you? Looking for said happiness won’t necessarily work easily as one might think, but your thoughts and actions will help. Any individual that chooses a lifestyle of contentment, positive environment, and good health is on the path to creating a happier self. As many people believe, money brings happiness; and if you’re poor, you must not be happy. Money does buy happiness—but only until a certain point. There’s no doubt that the luxurious life of fancy cars and million dollar houses make people grin from ear to ear. Contrary to that, according to a Princeton University study, after an annual income of $75,000, money doesn’t matter or bring more happiness. We suspect that this means, in part, that when people have a lot more money, they can buy a lot more pleasures, but there are some indications that when you have a lot of money, you will savor each pleasure less, said Kahneman, a professor at Princeton University.
