把一幅图像转化为二值图像，然后对二值图像进行行程编码和预测编码。-The image into a binary image, and then carried out on the binary image encoding and predictive coding itinerary.

用matlab对图象实施预测编码和解码，并将原图象与解码图象进行方差计算。-Using matlab implementation of image predictive coding and decoding, and the original image and the decoded image variance calculations.

利用一阶预测编码方法对图像进行编解码，具体实现的MATLAB代码-Using the first-order predictive coding method for image codec, concrete realization of MATLAB code
