Digital image comparing system

摘要

A system for comparing digital images, whereby a first and second data processing block receive respective data streams corresponding to a reference image and a detected image for comparison with the reference image. The data processing blocks detect reference points in the images, and generate data, which is supplied to a block for determining a first approximation of the function Ao relating the two images. The system also presents blocks for successively refining the function relating the reference image to the detected image. (FIG. 1)
