Abstract

In various fields such as movement detection, stereo matching, image morphing, image synthesis, and image recognition, automatic determination of the image correspondence is a very basic problem. In this paper, the relation establishing correspondence between a prototype and the images (i.e., warping function) is treated and the method of determination of such function is proposed. The proposed method is based on the variational principle. The warping function is determined as the solution which minimizes the brightness differences between the pixels under smoothness constraints. Examples on applications of the proposed procedure of determination of warping functions are presented which indicate the effectiveness of the method. ©2002 Scripta Technica, Syst Comp Jpn, 33(2): 22–30, 2002
