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......

...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......

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.

Recognition

...Recognition-based awards are given when employees go above and beyond. Employees are usually given plaques, trophies, certificates, small gifts, vacations, and dinners with company officials as a way to recognize their achievements. Cash awards are sometimes also given. Some examples of awards are outstanding achievement, excellent customer service, and length of service award. Awards are also given out to say “thank you”, “job well done”, and “you are valued as an employee”. When managers decide to give out recognition awards they have to have some guidelines that they need to follow. They need to first make sure that they have a clearly defined purpose for the award and that all team members know what it is. They also have to determine the type of award, who is eligible, and what criteria needs to be meet. Lastly they will need to decide if there is going to be award money, how it is going to funded and paid out and how the award is going to be given. Having a purpose for awards helps employees know why and how the award is going not only benefit themselves but the company as a whole. By informing employees about the purpose of the award all helps to encourage the behavior that is being awarded. Managers also need to make sure that eligibility is very clear. They need to make sure that all employees understand who is and who isn’t eligible without any room for misunderstanding. The criteria also needs to be very clear without any room for misunderstanding. Lastly,......

...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......

Gesture Recognition

...Gesture recognition is a topic in IT with the goal of interpreting human gestures via mathematical algorithms. Gestures can originate from any bodily motion but typically originate from facial or hand movements. Current focuses in the field include emotion recognition from face and hand gestures however the identification and recognition of posture, gait, proxemics, and human behaviors is also the subject of gesture recognition techniques. Although not wearable, the use of gesture recognition is, in fact, only possible through the use of the human body and motion (akin to any other wearable technology). In terms of fitness and health management, gesture recognition software is at the forefront of post injury and post-op physical therapy. Specifically, a company called GestureTek, through their proprietary Interactive Rehabilitation and Exercise System (IREX), “uses immersive video gesture control technology to place patients into virtual sport or gaming environments where they are guided through clinician prescribed therapeutic exercise regimes. The IREX virtual reality environments are specifically designed to rehabilitate the patient in the precise manner recommended by the clinician. The motion of the patient can be monitored and reported to describe functional improvement in the patient’s range of motion, control of motion and balance over the course of their treatment.” Being able to independently monitor progress, whilst also making rehabilitation fun,......

Face-to-Face Meeting Is the Conversation

...Hospital was facing with is the argument from labor union. Labor reunion is an organization within a business which represents the employees in order to protect and enhance employees’ rights and benefits, for example: wages, compensation, working condition (Reynolds, 2008). Among the new committee of Canterbury, the labor union was not included in it and they did not know the criteria that the hospital has used to choose the participants. Since the committee requested the involvement of the staffs, thus, as the function of protecting employees, the union had to acknowledge the information for them to ensure that the workload and status of the employee’s was remained and interpreted specifically in order for them not to be overloaded or lose face within public community. Loosing prestige and overloaded works demotivate staffs in cooperating with the business and paying effort to tasks. To summarize, even though Canterbury Hospital had a clear and appropriate general business goal of building the business sustainably, however, the poor HR strategies (Rilkoff, 2012) that the hospital has been implementing are not compatible with the enterprise’s objective. The issues that the organization has to solve in order to close the gaps within the company are: * Low employee autonomy * Low employee involvement and commitment * High labor conflict * Lacking of flexibility and unclear job design * Labor union conflict * Potential of unsecured prestige within......

...clumsy task. Thus, there exists a need for developing an efficient approach to search for the desired images form huge databases. Content Based Image Retrieval (CBIR) is one of the adopted solutions to the problem. Content Based Image Retrieval (CBIR) has become an important area for people to search and retrieve information. CBIR system retrieves the relevant images from the image data base for the given query image, by comparing the feature of the query image and images in the database. The CBIR utilizes visual contents of an image such as color, texture, shape, faces, spatial layout, etc., to represent and index the image database. These features can be further classified as general features such as color, texture, and shape, and domain-specific features such as human faces, fingerprints, etc. Texture Analysis has been one of the prominent topics in today’s world which is used in computer vision and pattern recognition. Texture Analysis is broadly justified into texture classification and texture segmentation. Texture classification is used to determine to which of a finite number of physically defined classes a homogeneous texture region belongs. The Texture Classification is done by using Discrete Wavelet Transform (DWT). However, the DWT can extract only three-directional (Horizontal, vertical, and diagonal) information from an image. To address this directional limitation, Gabor transform (GT) is proposed for texture image retrieval Corresponding Author: Aasish......

...and Recognition Blue Group Liz Crane Mark Glover Annice Lappin Tim Rowler Adele Vesty The Strategic Human Resource Management strategy that we will be focussing on for this presentation is ‘Reward and Recognition’. The award winning organisation that we have researched is Schweppes Australia, winner of the 2014 Australian HR award for the Best Reward and Recognition strategy, sponsored by Solterbeck. The format of our presentation will be to: 1. define the key terms, 2. present the research and literature focussing on both corporate and not for profit organisations 3. outline the award, 4. compare and contrast the award with the research of best practice of reward and recognition. 5. conclude with the benefits and limitations and alternatives of this Strategic Human Resource Management practice. Definition For the purposes of this presentation we have used the MIT Human Resources Division definition being, “The purpose of an employee recognition program is to recognize and reward work and behaviors that support/further the mission, goals, values and initiatives (of the organisation).” While Liz Prudden of San Diego State University separates this into two main categories, “The two types of reward and recognition are easily distinguishable: Monetary, receiving dollar incentives for performance and Non Monetary (NMR), various forms of "soft" recognition. Formal and Spontaneous are additional distinctions of Reward and......

Increased Contact Can Reduce the Other-Race Effect in Face Recognition

...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)...
