摘　　要：作者在文中给出了一种将圆环域图象展开成矩形图象的方法。这种方法主要采用八分之一圆扫描方法 ,快速找出某个圆的所有象素 。In this paper, a remarkable image processing method is presented which can easily and efficiently transform an image within the circular field into a rectangular one. Mainly by using an eighth circle scanning, the all pixels of a circle are fast found out. Then they are transformed into the corresponding ones of the spreaded image by using bilinear interpolation or extraction.
