基于vb的图像处理，可输入模板参数自行调校图像质量-Vb-based image processing, self-tuning parameters can be input template image quality

实现点的聚类，并用做图像分割，来源是文章：Self-Tuning Spectral Clustering (作者: Lihi Zelnik-Manor, Pietro Perona )(point clustering and image segmentation, algorithm is from paper:Self-Tuning Spectral Clustering(author: Lihi Zelnik-Manor, Pietro Perona ))

利用PCNN对图像进行简单的二值化处理，参数可自调(Using PCNN for simple two value processing of the image, the parameters can be self tuning)
