Image processing apparatus, image processing method, and image processing program

摘要

An image processing apparatus includes a distance information calculator (110) that calculates distance information corresponding to a distance to an imaging object at each of portions in an image; a feature data calculator (120) that calculates feature data at each portion in the image; a feature data distribution calculator (130) that calculates a distribution of the feature data in each of regions that are classified according to the distance information in the image; a reliability determining unit (140, 210) that determines the reliability of the distribution of the feature data in each of the regions; and a discrimination criterion generator (150, 220) that generates, for each of the regions, a discrimination criterion for discriminating a specific region in the image based on a determination result of the reliability and the distribution of the feature data in each of the regions.
