Abstract
A homography matrix generation apparatus () detects two or more key-point pairs from a first image () and a second image (). The homography matrix generation apparatus () detects, for each of the key-point pairs, a derived point pair, which is a pair of a point separated by a first distance in a first direction from a point on the first image () included in the key-point pair and a point separated by a second distance in a second direction from a point on the second image () included in the key-point pair. The homography matrix generation apparatus () uses each of the detected key-point pairs and the derived point pairs to generate a homography matrix () representing a homography from a point on the first image () to a point on the second image ().
