We put forward an compression algorithm based on isosceles right triangle according to the geometric similarity of binary images.
针对二值图像的几何相似性，本文提出一种基于等腰直角三角形的压缩算法。
Interpolation on gray images is needed in the course of geometric operation. Bilinear interpolation algorithm is effective, but its program is complex and the running time is longer.
几何运算要求对图像进行灰度值插值，双线性算法可产生令人满意的效果，但是程序较复杂，运行时间较长。
In this algorithm, many basic geometric transformations of digital images are unified. These transformations include scaling, rotating, shearing, flipping, and mirroring, etc.
