Available in PDF, EPUB and Kindle. Book excerpt: В реальных изображениях лиц большие визуальные вариации, такие как различия в выражении лица, его позиции, разный масштаб и освещение, наличие преград перед лицами и другие, вызывают трудности при отличии лица от фона изображения. В результате возникают области изображений, которые неправильно распознаются как лица (ошибки первого рода), тогда как эффективность алгоритмов распознавания лиц характеризуется низким числом таких ошибок, высокой скоростью обнаружения лиц и высокой скоростью обработки изображений. Таким образом, чтобы уменьшить число описанных областей, вместо того, чтобы разрабатывать точный алгоритм обнаружения лиц, который требует больших временных затрат на работу, после первичного обнаружения лиц будет добавлен этап их валидации. В настоящей статье предлагается новый быстрый метод валидации лиц. Он состоит из двух этапов: первый – определение кожи с использованием метода анализа значений YCbCr-цвета; второй шаг – обнаружение глаз и рта с использованием каскадного подхода. На втором этапе область лица-кандидата делится на две перекрывающиеся области, одна для модели обнаружения глаз, а другая для модели обнаружения рта. Алгоритм обнаружения лиц, основанный на методе опорных векторов, использовался для сравнения с предлагаемым решением. Результаты экспериментов на наборе данных FDDB показали лучшую производительность предлагаемого метода (время валидации 2 мс по сравнению с 500 мс у алгоритма, основанного на методе опорных векторов) при схожем числе ошибок первого рода.

Available in PDF, EPUB and Kindle. Book excerpt: Face recognition has received substantial attention from researchers in biometrics, computer vision, pattern recognition, and cognitive psychology communities because of the increased attention being devoted to security, man-machine communication, content-based image retrieval, and image/video coding. We have proposed two automated recognition paradigms to advance face recognition technology. Three major tasks involved in face recognition systems are: (i) face detection, (ii) face modeling, and (iii) face matching. We have developed a face detection algorithm for color images in the presence of various lighting conditions as well as complex backgrounds. Our detection method first corrects the color bias by a lighting compensation technique that automatically estimates the parameters of reference white for color correction. We overcame the difficulty of detecting the low-luma and high-luma skin tones by applying a nonlinear transformation to the Y CbCr color space. Our method generates face candidates based on the spatial arrangement of detected skin patches. We constructed eye, mouth, and face boundary maps to verify each face candidate. Experimental results demonstrate successful detection of faces with different sizes, color, position, scale, orientation, 3D pose, and expression in several photo collections. 3D human face models augment the appearance-based face recognition approaches to assist face recognition under the illumination and head pose variations. For the two proposed recognition paradigms, we have designed two methods for modeling human faces based on (i) a generic 3D face model and an individual's facial measurements of shape and texture captured in the frontal view, and (ii) alignment of a semantic face graph, derived from a generic 3D face model, onto a frontal face image.

Available in PDF, EPUB and Kindle. Book excerpt: It is with greatpleasure that we present the proceedings of the 4th International Symposium on Visual Computing (ISVC 2008) in Las Vegas, Nevada. ISVC o?ers a common umbrella for the four main areas of visual computing including vision, graphics, visualization, and virtual reality. Its goal is to provide a forum for researchers, scientists, engineers and practitioners throughout the world to present their latest research ?ndings, ideas, developments and applications in the broader area of visual computing. This year,ISVC grew signi?cantly; the programconsisted of 15 oralsessions, 1 poster session, 8 special tracks, and 6 keynote presentations. The response to the call for papers was very strong; we received over 340 submissions for the main symposium from which we accepted 102 papers for oral presentation and 70 papers for poster presentation. Special track papers were solicited separately through the Organizing and Program Committees of each track. A total of 56 papers were accepted for oral presentation and 8 papers for poster presentation in the special tracks. All papers were reviewed with an emphasis on potential to contribute to the state of the art in the ?eld. Selection criteria included accuracy and originality of ideas, clarity and signi?cance of results, and presentation quality. The review process was quite rigorous, involving two to three independent blind reviews followed by several days of discussion. During the discussion period we tried to correct anomalies and errors that might have existed in the initial reviews.
