Object region extraction device, object region extraction method, and computer-readable medium

Abstract

An object region extraction device according to an exemplary aspect of the invention includes: similar region calculation means 120 for calculating a region of high similarity to a feature extracted from an image; feature region likelihood calculation means 130 for calculating a likelihood of a feature region based on a position of the feature and the similar region; and object region extraction means 140 for extracting an object region based on the likelihood of the feature region. An object region extraction method according to another aspect of the invention includes: obtaining a feature from an image and extracting a position of the feature; calculating a region of high similarity to the feature extracted; calculating a likelihood of a feature region based on the similar region and the position of the feature; and extracting an object region based on the likelihood of the feature region.
