  • Differing region detection system and differing region detection method
    Patent number: 9424469
    Abstract: The present invention enables detection of a local differing region between images. Inter-image difference information indicating a difference in feature amounts for each subregion between first and second images is generated based on a first feature amount vector that is a set of feature amounts respectively corresponding to a plurality of subregions in the first image and a second feature amount vector that is a set of feature amounts respectively corresponding to a plurality of subregions in the second image, a differing region that is an image region that differs between the first and second images is detected based on differences in the respective subregions indicated by the inter-image difference information, and detection information that indicates a result of the detection is outputted.
