- 基于Sobel算子.该方法将图像划分成预先设定大小的网格,在两个尺度上对图像进行分析,完成图像的边缘检测。首先用Sobel算子求得图像边缘,依据网格内含有边缘像素的数目以及连通情况将不同的网格分别处理。 然后以网格为数据单元,在较大尺度上运用Sobel算子得到图像边缘。最后通过设定数据的优先级和使用形态学的方法合并两次计算边缘的结果。-Based on the Sobel operator. This method is an imag

- 当今影像数字化产生的位图影像,往往是以每像素三字节的格式表示的,这导致了大而难处理的位图。为减少这些存储开发了很多压缩系统。由Compu Serve开发的GIF(Graphic Interchange Format)系统通过把可能分配给一个像素的颜色数目减少到仅为256个的方法来研究问题,这意味着每个像素的值可以用一个字节而不是用三个字节表示。256个可能的像素值中的每一个都可借助于一个叫调色板的表与一个红、绿、蓝的组合联系起来。通过改
