Abstract— Recognition of face expressions of human beings by a computer is an interesting and challenging problem. Face is the most important feature of a human being. Everyone have a different face features and usually used as an identification. Recognizing different faces for humans is not a difficult task but it is difficult to identify different faces and their expressions by a system. Face expressions recognition can be used in a number of applications like authentication, security issues, and surveillance. Recently, Different Local Binary Pattern (LBP) operators have been applied into face recognition successfully. Center-symmetric Local Binary Pattern is a variation operator of LBP, which can reduce the dimensionality of LBP features, …show more content…
I. INTRODUCTION Face recognition is an active research area, and they can be used in wide range applications such as surveillance, authentication and security. Face recognition system can be used in two modes: Verification and Identification. In the identification process, the preprocessed image of a person is compared with face images of known individuals from a large database then returns the recognized identity. In the verification process, the preprocessed image of a person is compared with one face image from a database with the claimed identity. The system then returns the verification status by measuring the similarities between the two images. An efficient face recognition system could replace current identification methods like Personal Identification Number (PIN)-codes, passwords and Identification-cards, which according to could be exposed to security attacks, but also extremely reliable methods of biometric person identification, like fingerprint analysis and retinal or iris scans .In contrast, face recognition system is more accurate and reliable than all the proposed …show more content…
Face is the most important feature of a human being. Everyone have a different face features and usually used as an identification. Recognizing different faces for humans is not a difficult task for human beings but it is difficult to identify different faces and their expressions by a system. Face expression recognition can be used in a number of applications like authentication, security issues, and surveillance. Face is a complex multidimensional structure and needs a good computing technique for recognition. Various face expression recognition techniques include Local Binary Pattern(LBP), Principal Component Analysis(PCA), Local Discriminate Analysis(LDA), Linear programming. Basic technique used for face expression recognition is local binary pattern. Local binary pattern uses the concept of threshold with the neighbouring pixels. A number of variants of LBP exist like Rotation in-variant LBP, improved LBP, Advanced LBP, and Modified LBP. In this thesis we will implement CS-LBP for face recognition by three level face
5.2 GABOR-KPCA Results: Using Mahalanobis Cosine (MAHCOS) Distance Identification experiments: The rank one recognition rate of the experiments equals (in %): 80.00% Verification/authentication experiments on the evaluation data: The equal error rate on the evaluation set equals (in %): 4.17% The minimal half total error rate on the evaluation set equals (in %): 2.68%
, and forehead. The local feature that is mainly used here is wrinkle feature of some particular portions of the face like forehead region, eye corners regions, eyelids, mid of eyebrows. Using five distance values, six features namely feature 1 to feature 6 are calculated in the following way: Feature 1 = (left to right eye ball distance) / (eye to nose distance)
Figure 9.4 – Stream When the stream starts, OpenCV, which is running on the server, starts detecting and recognizing faces and displaying the results in a list that resides on the right sidebar. A green box appears, containing the information and the image of the recognized face. If the detected face is unrecognized, a red box appears, containing the face of the unknown individual. Figure 9.5 – Detecting & Recognizing Faces Right after an unrecognized face is caught, an email is sent as an alert for the security guards, containing the unrecognized face of the individual, alongside the date, the time and the IP Camera’s information.
Faces are a vital source of visual info about a person for instance, gender, emotion, mental states, trustworthiness, attractiveness, likeability, competence, and aggressiveness; the evaluation of it can take less than a second and remain constant even after much longer exposures (Willis & Todorov, 2006). Attractiveness is an important characteristic in mate choices and there are factors which affect what attractive is.

Having a time and attendance system to keep time is important. In 1888, Willard Bundy invented the time clock, but since that time, time clocks have not changed much. That is, until recently when MinuteHound brought their fingerprint time and attendance system to revolutionize the time clock industry. Wouldn 't it be great if you could know exactly where people are at all times? On average, businesses in the United States pay around $3.7 trillion on their payroll each year.
Dubbed the Valley Intruder or Night Stalker, Ricardo Leyva Munoz Ramirez famously known as Richard Ramirez, struck fear through the bones of many during his serial killing spree in the mid-eighties. Ramirez killed at least fourteen people in his spree while raping and torturing many more. His criminal beginnings turned to violence in June of 1984 with his first known slaying of 79-year-old Jennie Vincow. Vincow was sexually assaulted, stabbed and ultimately killed in her home. Authorities had not yet caught Ramirez after this brutal homicide, therefore he was free to continue his spree on countless more helpless victims.
Fingerprinting is method based on the uniqueness of the skin pattern - that is, each person has a completely individual pattern of papillary lines. These patterns do not change throughout life and have the property of recovering from damage to the skin in its previous form. On the one hand, this method almost completely eliminates the mistake, and on the other hand it is very cheap and easy to use (in contrast the method of identification of a person by DNA). Fingerprinting allows: 1) to identify the person who left the prints, according to the general and particular features of the papillary pattern displayed on them; 2) to exclude individual from among those who have touched the object; 3) to narrow the group of individuals suspected of the particular crime (for instance, provided that the imprint shows traces of a scar, a burn, a wart or some other distinctive feature).
After Judy Spross ' presentation on CAM and your reading in the textbook on CAM, which therapy (therapies) might you want to develop skills in and apply to your practice of nursing? In what context will you use it?(One paragraph) How did the presentation and reading open your mind more to this alternative therapy or were you already open to it before due to prior experience? (Second paragraph)
The authentication of Biometrics (i.e. the real authentication) which is used for identification and controlling the access which can be applied in the computer science. It is can be used in groups to identify the individuals under the surveillance. Biometric identifiers are used to labels the characteristics which can be measurable, the distinctive, and to describe the individuals. Biometric identifiers are being often categorized as behavioral versus physiological characteristics. Physiological are related to define the characteristics and the structure of the body.
Looking for the best biometric safe to keep all of your guns and valuables safe? Finding the best biometric gun safe can be difficult, especially if you don 't know where to start or don 't know very much about the various aspects of a biometric safes. Here are some tips for first choosing the aspects that are most important to you and then finding the best biometric safe to fit those aspects. Aspects The first step is to determine which aspects are the most important to you in a safe.
INTRODUCTION Now a day’s a facial recognition system is a computer application and it is used for automatically identifying or verifying a person . This is done by comparing selected facial features from the image and a facial database. Face Recognition System focuses on contactless man and machine interface. The human face plays an important role in our interaction and people’s identity.
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.
Artificial selection, sometimes called selective breeding, is the process of finding desired traits or characteristics in two separate individuals of the same species and breeding those individuals to hopefully produce an offspring with all the desired traits or characteristics combined. This process is done in a controlled environment by humans. Artificial selection has become huge in horse breeding. Owners can take a horse known for its speed and agility and mate with a horse with a good temperament and hopefully the offspring will be a combination of both horses. I have a big aquarium in my living room and other than a Plecostomus that aids in keeping the tank clean, the only fish I have are called Glofish.
A forensic test that was featured in the episode was the practice of fingerprinting and dusting for fingerprints at a crime scene. Fingerprinting has been used throughout human history as a means of solving crimes. One of the earliest examples of the use of fingerprinting in forensic science was during the Chinese Qin Dynasty, which recognized the importance of handprints as a form of evidence in investigating burglaries. The practice of fingerprinting in forensic science and crime scene investigation made significant progress in the nineteenth and twentieth centuries, when Thomas Taylor of the United States Department of Agriculture suggested in 1877 that bloody fingerprints could be used as evidence in crime scene investigations to determine
