摘要

提出了一种改进块截断编码的图像压缩算法。首先对待压缩图像进行差分，然后通过研究差分图像中不重叠小块的直方图提取边缘信息。图像被分为视觉活动块和视觉连续块，然后分别进行编码。

Image compression algorithm using local edge detection

An algorithm to improve block truncation coding for image compression is proposed. Images to be compressed are first differentiated and edge information is extracted by investigation of the histogram of small nonoverlapping blocks of the differential image. The image is classified into visually active and visually continuous blocks which are then coded individually.
