IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

Provided is an image processing device that can suppress deterioration in the accuracy of identifying a subject, even in cases where the shape of the subject in an image is deformed.;A feature amount calculation means 81 detects feature points from an image, and calculates, for each feature point, a local feature amount for the feature point on the basis of a peripheral region of said feature point, including said feature point. A correlation identifying means 82 specifies the correlation between feature points in a first image and feature points in a second image on the basis of the local feature amount of each feature point in the first image and the local feature amount of each feature point in the second image. A partial region detection means 83 detects, from one of the first image or the second image, partial regions each including a feature point in said image. A matching means 84 determines, for each partial region, whether or not a subject in the first image is identical with or similar to a subject in the second image on the basis of the feature point included in the partial region and a feature point corresponding to the feature point.

主权项

1. An image processing device comprising:
a processor configured to function as: a local feature amount calculation configured to detect feature points in an image and calculates, for each of the feature points, a local feature amount of the feature point, based on a peripheral region of the feature point, the peripheral region including the feature point; a correlation identifying configured to specify, based on the local feature amount of each of the feature points of a first image and the local feature amount of each of the feature points of a second image, a correlation between the feature point of the first image and the feature point of the second image; a partial region detection configured to detect partial regions including the feature points in an image of one of the first image and the second image; and a matching configured to determine, for each of the partial regions, whether or not an object in the first image and an object in the second image are the same or similar based on the feature points included in the partial region and the feature points corresponding to the respective feature points.
