The useless samplings and accumulations of randomized Hough Transform (RHT) are largely reduced with the help of the ellipse's conic control point constraint and the constraint of the normals at the endpoints of a chord. The fuzzy confidence based on vision perceptual grouping is used to further eliminate false candidate ellipses introduced by the same(More)
In order to recognize and track all of the heads exactly in top view images, a novel approach of 3D feature extraction of heads based on target region matching is presented. The main idea starts from the disparity of head region, which is generally extracted in global dense disparity image obtained by block matching method. Deferent from the block matching,(More)
