Cheby 四种基本滤波器(Cheby four basic filter)

mage compression is one of the most important step in image transmission and storage. Most of the state-of-art image compression techniques are spatial based. In this code, a histogram based image compression technique is implemented based on multi-level image thresholding. The gray scale of the image is divided into crisp group of probabilistic partition
