In the paper an face location and eye detection method is proposed based on active infrared source system, which is to solve the problems of pupil threshold segmentation according to from coarse and fine strategy. This method use bright pupil and dark pupil difference scheme. Firstly, we collect a lot of dark images to train classifiers make use of Haar features, boosting them to be a strong classifiers...
The automatic objects tracking in videos plays important roles in computer vision applications. In this paper, we propose an automatic object tracking method hybrid with GMM and edge orientation histogram based CamShift. GMM is applied to detect objects motion. Different moving objects are separated by connected component analysis. And CamShift is processed by using edge orientation histogram to track...
In this paper, a novel variable-domain approach to curve evolution for image segmentation was proposed, being based on a statistical active contour model using level sets. The essential idea is to re-define the computing domain in image repeatedly, by separating the segmentation procedure into several individual phases, for images composed of an infinite number of regions. By our algorithm, the work...
Facial action units (AUs) recognition is a challenging problem with many applications and is rapidly becoming an area of intense interest in research field of machine vision. Nonadditive AU combinations in which the appearance of the constituent AUs does change greatly increase the difficulties of AU recognition. Most AUs recognition methods treated each AU combination as a new AU. However, these...
