Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To make both search time shortening and correspondence detection accuracy compatible by detecting an area similar to an initially set template area in the image area on a search-source side and setting the area including the area as a new template. SOLUTION: A feature extracting means 1 obtains feature value data C and D by extracting feature values of respective pixels (a) and (b) of corresponding point searching in images A and B to be processed. Then an initial template setting means 2 decides pixels having feature values applicable to a set reference value among the pixels in the specific area (a) of the image as a correspondence search source as an initial template E. Then a template generating means 3 searches for an area having a close feature point at the periphery of the initial template E and integrates the area with the template E to obtain a new template. Thus, a multi-stage template F is generated. Then a correspondence search means 4 performs a matching process by using smaller templates from the maximum generated template in the search area (a) of a search-destination image B to determine corresponding points.
