The abnormal function of cells can be detected by anatomic or physiological registrations. Most of modern approaches, as ultrasound, RMN or CT, show anatomic parametric modifications of tissues or organs. They highlight areas with a larger diameter 1

In this paper we present an improved method for image partition. Image partition plays an important role in video segmentation techniques; it uses different region growth algorithms for separating an image into regions and objects. This enhances the
