全变差模型和相位一致性结合提取图像的边缘信息，有效的处理了噪声的影响-Total variation model and the phase coherence combined edge image information extraction, effective treatment of the effects of noise

Wepropose a novel method for 3D image segmentation, where a Bayesian formulation, based on joint prior knowledge of the object shape and the image gray levels(In addition, we evaluate the performance of the level set representation of the object shap
