摘要：The Active Shape Model - ASM is a class of deformable models that relies on a statistical a priori knowledge of shape for the segmentation of structures of interest [5]. The main contribution of this work is to integrate a new a priori knowledge about the spatio-temporal shape variation in this model. The aim is to define a new more stable method, allowing the reliable detection of structures whose shape changes considerably in time. The proposed method is based on two types of a priori knowledge: spatial and temporal variation of the shape of the studied structure. It was applied first on synthetic sequences then on scintigraphic sequences for tracking the left ventricle of the heart. The results were encouraging.
