Résumé :

In this paper, we propose to use the method ofpiecewise constant level set(biphase and multiphase) with theMumford-Shah model. For image segmentation, the Mumford-Shah model needs to find the regions and the constant valuesinside the regions for the segmentation. For this purpose, weneed to use a variational approach generally used in image segmentationwhich allow the extraction of the regional information(mean and variance) in an adaptive manner. Finally, we validatethe proposed models by numerical results for radiographic imagesegmentation.
