Abstract:
Line images in horizontal and vertical directions are detected from input image data, and an intersection of the line images is calculated. the calculated intersection is regarded as a feature point of input image data. Thus, it is possible to easily and promptly extract, from image data, a feature point that allows specifying the image data appropriately.
