Abstract
Hough transform is performed on the point groups forming two dimensional data to generate a plurality of loci respectively corresponding to each of the point groups in a Hough voting space. When adding a voting value to a position in the Hough voting space through which the plurality of loci passes, addition is performed by varying the voting value based on a level difference between first and second signals respectively indicated by the two pieces of frequency decomposition information.
