Evaluations of the state-of-the-art of both academic face recognition algorithms and commercial systems have shown that performance of most current technologies degrades due to the variations of illumination. We propose a novel technique for face recognition under generic illumination in this paper, namely, calibrating an input face image to an image under canonical illumination, named as face ...
As it is simple and convenient to operate face recognition system, and this kind of system is without invasive, making face recognition technology become an important research direction of biometric identification. Face recognition technology involves digital image processing, pattern recognition, computer vision, neural networks and other research areas, has important research values. PCA algo...
In this study, we analyze the role of several linguistic cues (prosodic units, pitch contours, discourse markers, morphological categories, and gaze direction) in French turntaking face-to-face interactions. Specifically, we investigate vocal and gestural backchannel signals (BCs) produced by a recipient to show his active listening. We show that some particular pitch contours and discursive ma...
Does audio computer-assisted self-interviewing (ACASI) produce more valid reporting of sexual activity and related behaviors than face-to-face interviews or self-administered interviews? This analysis, based on data collected from over 6,000 unmarried adolescents in two districts of Kenya--Nyeri and Kisumu--indicates substantial and significant differences in reported rates of premarital sex ac...
Banner advertising is a popular means of promoting products and brands online. Although banner advertisements are often designed to be particularly attention grabbing, they frequently go unnoticed. Applying an eye-tracking procedure, the present research aimed to (a) determine whether presenting human faces (static or animated) in banner advertisements is an adequate tool for capturing consumer...
1 2 Abstract This paper describes a multi-modal corpus of hand-annotated meeting 3 dialogues that was designed for studying addressing behaviour in face-to-face con4 versations. The corpus contains annotated dialogue acts, addressees, adjacency pairs 5 and gaze direction. First, we describe the corpus design where we present the 6 meetings collection, annotation scheme and annotation tools. The...
Security and authorization of person is a crucial part of any industry or organization. There are many techniques are available in the industry .Techniques are Password management system, ,finger print, signature matching etc., one of them is face recognition system. It has received substantial attention from researchers in various fields of science such as biometrics and image processing and F...
A new algorithm for planar face segmentation in range images is introduced. The segmentation is based on a combination of recursive adaptive regression model prediction for detecting range image step discontinuities which are present at object face borders and of a region growing on surface lines. Border pixels are detected in two perpendicular directions and detection results are combined toge...
Excessive gingival exposure at the maxillary anterior region during not only smiling (a gummy face) but also at rest creates both functional and aesthetic problems for patients. We herein introduce a unique treatment procedure for mandibular retrognathia with a gummy face. This procedure combines conventional Le Fort I osteotomy and following corticotomy at the anterior region of the maxilla. S...
We demonstrate the construction of diamond photonic crystal structures by the translation of a multi-beam interference pattern. Using phase shift of each beam, the double-exposed interference patterns can be aligned in the [111] direction for a face-centered cubic (FCC) and [210] direction for a body-centered cubic (BCC), respectively, producing diamond D from FCC and BCC-diamond like structure...
