Title: Image analyzer
Inventor: ONOYAMA TAKASHI
IPC: G06T1/00
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To make fast graspable the change with time of an object by comparing the images photographed on different dates with each other to automatically grasp the change with time. SOLUTION: An image information recording part 101 stores the image information on the satellite images, aerial photographs, etc., and a rotation correction part 102 corrects the angles of rotation of plural images stored in the part 101 to perform the differential analyses among these images. A parallel movement correction part 103 moves the images corrected at the part 102 in parallel to each other to correct the positions of these images on a two- dimentional plate. A differential image extraction part 104 extracts the differences among the images which undergone the position matching by the rotations and movements of them and rocords these images at a differential image recording part 105. A display control part 106 shows one or both of image information which are stored in both parts 101 and 105 on a display device 108 based on the input received from an input device 107.  As a result, the change with time of an object can be fast grasped from among a large number of images.
