Title:
SIMILAR REGION DETECTION DEVICE, SIMILAR REGION DETECTION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/060147
Kind Code:
A1
Abstract:
A similar region detection device according to an embodiment is provided with an acquisition unit, a feature point extraction unit, a matching unit, an outermost contour extraction unit, and a detection unit. The acquisition unit acquires a first image and a second image. The feature point extraction unit extracts feature points of the first image and the second image. The matching unit associates a feature point extracted from the first image and a feature point extracted from the second image, and detects an inter-image correspondence point. The outermost contour extraction unit extracts an outermost contour from the first image and the second image. The detection unit detects similar regions, which are partial regions that are similar to each other in the first image and the second image, from the first image and the second image on the basis of the outermost contours and the number of correspondence points.
