FACE DETECTION SYSTEMS BASED ARTIFICIAL NEURAL NETWORKS ALGORITHMS:
Abstract: Face detection is one of the most relevant applications of image processing and biometric systems. Artificial neural networks (ANN) have been used in the field of image processing and pattern recognition. There is lack of literature surveys which give overview about the studies and researches related to the using of ANN in face detection. The novelty of this work comes from the integration of A facial recognition system is a computer application for automatically identifying or verifying a person from a digital image or a video frame from a video source. I would like to focus on some well-known face detection techniques and then some feature detection methods because until and unless we extract the important features (eyes, nose, mouth) from a face we won’t be able to uniquely identify the person properly. The dissimilarity between the two shapes is computed as some of …show more content…

In the first step, we localize the face region that means we are anticipating those parts of an image where a face may present. In the second step we normalize the detected region, so that the alignments of various facial features are in the proper location. In the third step we extract various facial features like eyes, nose, mouth, etc [1]. And in the forth step, we actually verify whether the anticipated parts are actually carrying out a face or not. We are doing this using some rules, template or image databases. The concept of extraction can be implemented by various techniques. There are a huge number of papers regarding the literature survey of face detection [2]. Most of the earlier work was on the frontal upright face, but recent work is mainly focus on non-frontal face with variation in their alignment. Also instead of still image, they are considering video stream

    Throughout history, photographs have been known to depict and represent culture, character, information, and ideology. Through specific elements of form, and close scrutiny, photographs give a representation of the “bigger picture” by providing content and invaluable information that text, on its own, does not produce. Dr. Carol Payne, a professor of art history at Carleton University, wrote an essay in 2012 for the Oxford University Press. This essay focused on the relationships between photographic images, Canadian culture and identity, and indigenous people. Her thesis was to discuss how an image can present a sense of national identity (Carol Payne 310).

    Another alternative to decrease police misconduct is through the use of body cameras which would hold officers accountable for their actions. Often, commanding officers exercise little supervision over the daily activities of their officers. Not only do officers patrol alone, but they are authorized to quickly create solutions and sanctions on the spot. This provides officers the freedom to get away with both minor and major violations to outright crimes. A tactic to prevent this from occurring is to mount body cameras on officers while on duty.

    Everyday we encounter new and familiar faces. We are able to distinguish our mother’s face from a stranger’s face due to the facial recognition processes that we have stored in our brains. Facial recognition is one of the many processes of object-recognition. Many of us are not aware of the brain’s role in facial recognition because it is a process that we are not consciously doing. Face recognition differs from object recognition in a few ways.

    Abstract— Face recognition is one of the most important biometric and face image is a biometrics physical feature use to identify people. Major and Minor segments of face space are eyes, nose and mouth. In biometrics quality face is the most imperative characteristic method for recognize individuals. High intra-class variety inside face pictures of the same individual is the significant issue in face distinguishment. Posture, statement and enlightenment are in charge of high intra-class variety.

    Face recognition technology [1] is the least intrusive and fastest biometric technology. It works with the most obvious individual identifier – the human face. Instead of requiring people to place their hand on a reader (a process not acceptable in some cultures as well as being a source of illness transfer) or precisely position their eye in front of a scanner, face recognition systems unobtrusively take pictures of people 's faces as they enter a defined area. There is no intrusion or delay, and in most cases the subjects are entirely unaware of the process. They do not feel "under surveillance" or that their privacy has been invaded.
