An image-based approach provides an efficient way for visual speech synthesis. In an image-based visual speech synthesis system, a few lip images, namely visemes, are used for ge...
In this paper, we address the problem of fluid motion estimation in image sequences. For such motions, standard optical flow methods, based on intensity conservation and spatial...
In this paper we address the object recognition problem in a probabilistic framework to detect and describe object appearance through image features organized by means of active c...
Grouping algorithms based on histograms over measured image features have very successfully been applied to textured image segmentation [2, 11, 6]. However, the competing goals of...
Ridges and valleys are earth’s relief structures. They can have an imaging counterpart provided we model a digital image as a landscape by considering grey level values as heigh...
