采用邻域差值特征模板的立体匹配方法
- 算法给出一种图像匹配方法，通过计算一幅图像中间隔一定距离的两点的像素邻域差值作为特征模板，再计算另一幅图像中在同一扫描线上间隔同样距离的像素邻域的差值，将它与特征模板的偏差作为匹配标准，偏差最小的点就认为是匹配点。

- 霍夫曼编码的基本方法是先对图像数据扫描一遍，计算出各种像素出现的概率，按概率的大小指定不同长度的唯一码字，由此得到一张该图像的霍夫曼码表。编码后的图像数据记录的是每个像素的码字，而码字与实际像素值的对应关系记录在码表中。-Huffman coding method is first scanned image data again, to calculate the probability of a variety of pixel specify a different length uniq
