Abstract

Abstract

In this paper, the algorithm of using B spline function for geometric transformation of digital image is presented. Given a group of special regular controlling points, B spline function for transformation is formed. The algorithm guarantees precise correspondence between controlling points, higher precision can be obtained. It can be implemented in a minicomputer digital image processing system with a special hard-wired device.This paper also points out that the geometric window transformation can be implemented automatically.
