This paper proposes a new region extraction algorithm based on cellular automaton operation, which only utilizes the region boundary information of the image. A simple pixel circu...
Abstract. We present a method for finding the boundaries between adjacent regions in an image, where “seed” areas have already been identified in the individual regions to be...

3D-shape description requires the partition of objects in different parts. In this paper, we propose a new approach based on the analysis of a 3D skeleton. The skeleton is a repre...
This work is motivated by the need for visual information extraction and management in the growing field of content based image retrieval from medical archives. In particular it f...
We propose a scheme to introduce directionality in the Random Walker algorithm for image segmentation. In particular, we extend the optimization framework of this algorithm to com...
