Document Type and Number:
WIPO Patent Application WO/2022/239096
Kind Code:
A1
Abstract:
An image analysis device 1 includes: an acquisition unit 101 that acquires an input image; a detection unit 102 that analyzes the input image acquired by the acquisition unit 101 to detect a region and a type corresponding to a configuration image constituting the input image; an expansion unit 103 that expands the region detected by the detection unit 102; an evaluation unit 104 that evaluates, using a rule corresponding to the type, an image included in the region expanded by the expansion unit 103; and an output unit 106 that, on the basis of an evaluation results evaluated by the evaluation unit 104, outputs a region corresponding to the configuration image, said region being from the region expanded by the expansion unit 103.
