...Intel® Technology Journal | Volume 18, Issue 4, 2014 HETERogEnEoUs FAcE REcognITIon: An EmERgIng TopIc In BIomETRIcs Contributor Guodong Guo West Virginia University An emerging topic in biometrics is matching between heterogeneous image modalities, called heterogeneous face recognition (HFR). This emerging topic is motivated by the advances in sensor technology development that make it possible to acquire face images from diverse imaging sensors, such as the near infrared (NIR), thermal infrared (IR), and three-dimensional (3D) depth cameras. It is also motivated by the demand from real applications. For example, when a subject’s face can only be acquired at night, the NIR or IR imaging might be the only modality for acquiring a useful face image of the subject. Another example is that no imaging system was available to capture the face image of a suspect during a criminal act. In this case a forensic sketch, drawn by a police artist based on a verbal description provided by a witness or the victim, is likely to be the only available source of a face of the suspect. Using the sketch to search a large database of mug-shot face photos is also a heterogeneous face recognition problem. Thus it is interesting to study the HFR as a relatively new topic in biometrics. In this article, several specific HFR problems are presented, and various approaches are described to address the heterogeneous face matching problems. Some future research directions are discussed as well to advance...

...Abstract— Face recognition is a biometric system used to verify or identify a person from a digital image. This involve extracting features of face and then recognize it, regardless of expression, lighting, illumination, transformations (translate, rotate and scale image), ageing and pose. The existing approaches are deblurring based, joint deblurring and recognition, deriving blur invariant features and direct approach, which uses convolution model for performing face recognition in the presence of blur. So these methods cannot handle non uniform blurring situations that frequently arise from rotations and tilts in hand held cameras. In this paper, face recognition is done, in the presence of space varying motion blur. We have taken the concept that the set of all images obtained by non-uniformly blurring a given image form a convex set. We develop an algorithm based on TSF (Transformation Spread Function) model. On each focused...

...Re Face Recognition Paper Adriana Zachry Psych/560 November 13, 2012 Christopher Wessinger Face Recognition Paper Face recognition develops slowly through life. Recognizing a face can be a difficult for the individual and also for the brain system that processes. The complexity of recognizing individual faces can be a difficult task at times. Recognizing faces also includes looking at an individual’s emotional expression and then, being able to take that information and processing it. This can be more complicated because facial recognition also includes the processing of emotions and emotional content. The brain can easily recognize a face without encountering any complications. Facial identification is essential for recognition of people in the social context within our society. The basic process of visual perception includes translating incoming stimulus into a perception and memory. When an individual will initially sees an object or a person, this information then gets processed through the brain. Bottom up and top down processing plays a critical role in object recognition. When we first look at an object we process it. This is called bottom up processing. When people apply previous knowledge to that object, it is known as top down processes. There is also a process when we recognize an object; we match an incoming object with stored information that helps us to recognize what is before us. A study was conducted by Palmer, Rsich and Chase on the perspective...

...DECO HCI Seminar WS 2010/2011: Student projects stefan.bachl January 19, 2011 Tags: android, application, hci, ios, mobile, open data, prototyping, seminar This semester’s design task of the Human Computer Interaction seminar at DECO was to create, prototype and evaluate a location-aware mobile application that uses open data. Five teams of three students each completed the seminar, resulting in creative, useful and sometimes also provoking use of fictitious open data. As open datain Austria is in its infancy (for more information visit open3.at orgov.opendata.at), teams had difficulties finding existing open (government) data sources. Some teams solved this problem by augmenting their application ideas with user-generated content as the main data source. The horizontal prototypes for the evaluation were implemented with various tools, includingTitanium Mobile, Sencha Touch and also native development on iOS and Android platforms. We proudly present the mobile application concepts of our five participating student teams. Note that most screens contain static data used only for the evaluation of the prototypes. The applications are (also if stated otherwise) not available on any store at the moment. ------------------------------------------------- Team AAA_Team: RegioBioFood Aleksandar Djordjevic, Alex Brandner, Andreas Hörmann RegioBioFood is an application which helps people to find bio products in an easier way, only by few clicks on their android smart phone.

This has been a problem for facial recognition system for decades. Approach: For this reason, our study represents a novel technique for facial recognition through the implementation of Successes Mean Quantization Transform and Spare Network of Winnow with the assistance of Eigenface computation. After having limited the frame of the input image or images from Web-Cam, the image is cropped into an oval or eclipse shape. Then the image is transformed into greyscale color and is normalized in order to reduce color complexities. We also focus on the special characteristics of human facial aspects such as nostril areas and oral areas. After every essential aspectsarescrutinized, the input image goes through the recognition system for facial identification. In some cases where the input image from the Web-Cam does not exist in the database, the user will be notified for the error handled. However, in cases where the image exists...

...Other-Race Effect in Face Recognition As humans, we come into contact with many faces in a day. The capability of these homosapiens to precisely distinguish thousands of faces is incredible seeing that all faces have approximately the similar arrangement. Nevertheless, this “gift” does not spread similarly the same to all faces. Sporer (2001) stated that humans commonly exhibit weaker remembrance for faces of another race compared to own-race faces (as cited in Hancock and Rhodes, 2008). The majority of us must have heard this line, “How am I to know if I have ever seen the person previously? They all look the same to me.” When we hear an individual say this, we’re prone to assume that the individual is racist, but is it possible that there could be a particular theory behind the notion? This occurrence is identified as the Other-Race Effect (ORE) (ORE). Tanaka, Kiefer and Bukach (2004) mentioned that the Other-Race Effect (ORE) states that individuals have a higher probability to recall and identify faces of people who are from their own race rather instead of their own racial group. Extensive evidence has proven that adults are better at distinguishing faces of their own race than those of unfamiliar races (Meissner and Brigham, 2001). The Other-Race Effect (ORE) are not stemmed from the intrinsic variances in the discriminability of diverse populations of faces. Instead, it is due to the different approaches people process own and other-race faces (Rhodes et al., 2009)...

...TO: J Corporation FROM: Yizhen Gong RE: §357(c) gain IRS examination DATE: October 13, 2014 Facts Joe owns 100% of the stock of J Corporation. Joe plans on contributing a parcel of land to J co. having a fair market value of $1.5 million and a basis of $350,000. Further, the land is subject to a mortgage of $1.2 million. To avoid the gain that would result on this transaction, due to §357(c), Joe plans on contributing a promissory note to J Corporation of with a face value of $850,000. He claims that this note will have a basis equal to its face value thus eliminating the gain caused by §357(c). Issues Whether Joe’s transfer of a promissory note to its wholly owned corporation, in an amount equal to the excess of liabilities over the basis of assets contributed in a §351 transfer, avoids §357(c) gain recognition? Can he increase the basis of the assets by transferring his own promissory note to the corporation? Conclusion 1. Joe received stock valued at $300,000 and thus realized a gain of $1,150,000 ($300,000+$1,200,000-$350,000). §357(c) requires Joe recognize a gain of $850,000 ($1,200,000-$$350,000). 2. It depends on whether Joe’s note has a basis in Joe’s hands for purpose of section §357(c). Analysis 1. Under §357(c), no gain or loss is if property is transferred to a corporation solely in exchange for stock of that corporation if, immediately upon the transfer, the transferors are in control of the corporation. Joe transferred...

...technology is finally able to handle the extensive amounts of equations going on to create the virtual neurons necessary to recognize images and or speech. Watch Video at this link: What is DeepFace? 'Human-Level' Face Matching, Explained https://www.youtube.com/watch?v=13FZHiXJSsE Application: Although the concept of facial recognition is not a breakthrough, the uses for it are. Facebook states that the DeepFace technology will be used to improve user privacy to dispel privacy concerns it has had in the past. DeepFace will be able to identify the user in a photo and notify them before allowing them to be tagged in it without their permission. This is especially useful as it will allow the user to blur out their face in images that may be embarrassing or even incriminating. This will notify uses whether the person uploading the photo is a friend or a stranger but only allows users to see the identities of the people they are already friends. Google and the government have taken a special interest in this application. Google has developed its own variation of this technology called FaceNet that boasts more than 86% accuracy at identifying whether images are the same person, while DeepFace has an accuracy score of 97% using the same recognition data set called Labeled Faces in the Wild. The difference between the FaceNet and...

...Punch The Punch The most important thing to remember about leaving the past behind is to never look back, no matter how tempting it might be. That means leaving the physical and mental pain with the past. They never explained how much your fist hurts after that swing. The fact that the cheekbone of boy your age is as firm as the cement floors just a few metres away. This is the easy pain though. The pain which hurts most is when your throbbing fist becomes still and the adrenaline you felt is all but a memory. I tried to argue to the ref that he was being a grub all game, that I was provoked, that he threw the first punch and that some sort of justification would ease my pain. Constant vulgarities being tossed at me, elbows to the face, rubbing my face into my own home turf ground, tasting the bitterness of the mud and feeling the dirt seeping into my pores. There’s a limit to how many times you can tell someone to back off, before the testosterone within you breaks through your self-control barrier and forces you to make sudden decisions which affect your life. So I threw my punch. Then he threw his. Exchanging rapid punches like an eager child opening a birthday present. Constant yelling from the sidelines, in the background; whether it was abusive or positive comments. We didn’t hear the words, not in our current state. Those punches and jabs were far from swift though. Still half the time they scraped past our slippery shoulders. That didn’t die down the velocity of the ‘fight’...

...ACCURATE EYE CENTRE LOCALISATION BY MEANS OF GRADIENTS Fabian Timm and Erhardt Barth Institute for Neuro- and Bioinformatics, University of L¨ beck, Ratzeburger Allee 160, D-23538 L¨ beck, Germany u u Pattern Recognition Company GmbH, Innovations Campus L¨ beck, Maria-Goeppert-Strasse 1, D-23562 L¨ beck, Germany u u {timm, barth}@inb.uni-luebeck.de Keywords: Eye centre localisation, pupil and iris localisation, image gradients, feature extraction, shape analysis. Abstract: The estimation of the eye centres is used in several computer vision applications such as face recognition or eye tracking. Especially for the latter, systems that are remote and rely on available light have become very popular and several methods for accurate eye centre localisation have been proposed. Nevertheless, these methods often fail to accurately estimate the eye centres in difficult scenarios, e.g. low resolution, low contrast, or occlusions. We therefore propose an approach for accurate and robust eye centre localisation by using image gradients. We derive a simple objective function, which only consists of dot products. The maximum of this function corresponds to the location where most gradient vectors intersect and thus to the eye’s centre. Although simple, our method is invariant to changes in scale, pose, contrast and variations in illumination. We extensively evaluate our method on the very challenging BioID database for eye centre and iris localisation. Moreover...

...Project – an Automated Make-up color selection system. Supervisor – Dr. H.L.Premarathne Field(s) of concern – Artificial Neural Networks, Fuzzy Logic, Image Processing, Data Classification, make-up Background: Women typically like to be in the centre of attraction of other the people. In order to be elegant looking and to get the attention of others, ladies often use make-up. Make-up is a favorite topic of women, and is a primary concern, not only when attending functions such as weddings, parties, but in day-to-day life when going for work too. The success of make-up relies on how well one can select the colors that matches her skin color, eye color, shape of the face and other relevant features. Make-up is also an art; hence one should have a good artistic eye to select the make-up which suits her. Inappropriate applying of make-up will cause a person to be in the centre of sarcasm and annoyance, instead of being in the centre of attraction. This is why; ladies often take the service of a beautician. A beautician is a professional who’s trained and who has expertise knowledge on beauty therapy and make-up. With experience, a beautician can match the make-up colors to suit a person, according to her appearance and personality. However, one does not need the help of a beautician, if that person can choose the appropriate make-up colors for herself. Introduction: Selection of colors for a make-up is vital for a Beautician as well as for any lady who rely on make-up...
