This paper proposed a framework of segmenting multiple targets basing on multiple shape priors. The key novel idea in the proposed framework is the shape degeneration model. By breaking the balance between the competition regions adaptively, the proposed model can degenerate the region which is with low similarity with any of the shape priors, until this region completely disappears. Meanwhile the proposed model can also merge the regions that belong to a single object automatically, which is especially important when some of objects are in partial occlusion. Additionally, we presented two new models in the proposed framework. One is a new local model of active contour, which can segment image with intensity inhomogeneity correctly. The other is a generalized shape prior model, which extends the intrinsic alignment model, and can take extra affine parameters into account in the alignment process of shape priors. Experimental results show the validity of the proposed method.
