The image segmentation methods based on Markovian as- sumption consist in optimizing a Gibbs energy function which depends on the observation field and the segmented field.. This

Illustration of the proposed method : (a) regions for feature calculation (orange : sliding window, red : superpixel) ; (b) example image from the L ´ Or´eal database (this image

The approach is based on using a large number of realizations of random markers to build a probability density function (pdf) of contours, starting from a standard watershed

Nevertheless, Maxwell models constitute an ideal framework, due to their mathematical simplicity, in order to study non-trivial features of the Boltzmann equation, such

We recall the classical way of building a standard BPT, as proposed in the pioneering article [4]. The BPT construction is a bottom-up process. It proceeds from the determination of

Given any similarity measure between re- gions, satisfying some weak constraints, we give a general predicate for answering if two regions are to be merged or not during

Second, we generalize the enhanced fuzzy c-means algorithm [4] to color images (in fact any N -d image) by using a quantization of the color space.. Thus, we keep the ability of
