Abstract: A level-set based multiphase active contour model is proposed for medical image segmentation in this paper. The proposed method allows multiple objects with very different features to be jointly segmented by simultaneously evolving multiple active contours, each responsible for the segmentation of a single object. In this model, the forces exerted on each active contour mainly consists of two components. The first component makes use of boundary as well as regional information present in the input images. The second component is used to impose the so-called medial axis constraint, which is related to the force induced by interaction of multiple active contours. Experimental results on real medical images are also presented to show that the proposed method has good performances on topology preservation of multiple contours, as well as joint segmentation of similar objects in multiple images.
