DIFFERING REGION DETECTION SYSTEM AND DIFFERING REGION DETECTION METHOD

摘要

In the present invention, local differing regions between images are detected. On the basis of a first feature quantity vector, which is a collection of feature quantities respectively corresponding to a plurality of partial regions in a first image, and a second feature quantity vector, which is a collection of feature quantities respectively corresponding to a plurality of partial regions in a second image, inter-image delta information is generated that indicates the feature quantity delta for each partial region between the first and second images, and on the basis of the delta that is at each partial region and is indicated by the inter-image delta information, a differing region is detected that is an image region at which there is a difference between the first and second images, and detection information indicating the detection results is output.
