Traditional optimal thresholding methods are very popular and efficient in the case of bi-level thresholding. But they are very computationally expensive when extended to multilevel thresholding since they exhaustively search the optimal thresholds to optimize the objective functions. In this paper, a fast scheme using genetic algorithms is proposed to render these optimal thresholding techniques...
In this paper we propose an algorithm for image segmentation in which contours and regions cooperate. In order for this cooperation to be efficient, the role of contour pixels and region pixels should be considered differently. Region pixels carry information about the content of the image. They are defined on a lattice identical to the image lattice. Contour pixels carry information about regions...
