Hi This mfile is source code for image segementation using active contour models [Snake]. It found the objects in imaages.

从ML-EM 重建算法入手，分析了贝叶斯模型的一些关键点，针对采用传统方法求解MAP问题的局限性，提出一种用于正电子成像的贝叶斯神经网络重建算法，为了保留边缘信息，引入了二进制的保边缘变量，并应用共轭神经网络求解，模拟的重建结果表明，应用这种算法可以得到比ML-EM 算法更好的重建图像@-From the ML-EM reconstruction algorithm start with an analysis of Bayesian model some of the key points,

用于提取管状结构的提取，避免周围特征的感染，精确度更高。-OOF:Optimal Oriented Flux.Model the tubular struture for 3D image.

通过三维模型生成的各种姿态图像与输入图像对比，找出匹配度最高的图像，即可估计出输入图像的目标姿态。-The image with the best matching degree can be found images which generated 3D model by matching with input image, and the pose is estimated.
