Abstract
An information processing device according to the present invention includes: a feature point sampling unit that generates, based on an initial value of a feature point used for registration of an object included in a target image to be processed, a feature point hypothesis that is a group of a plurality of the feature points in the target image; an image degradation unit that generates a degraded image that is a degraded image with degrading a reference image used for processing the target image, based on the feature point hypothesis and a degradation parameter for degrading an image; and a reliability calculation unit that calculates a reliability of the feature point hypothesis, based on the target image, the degraded image, and the feature point hypothesis.
Claims7
An information processing device comprising:
- a memory;
- and
- at least one processor coupled to the memory,
- the processor performing operations, the operations comprising:
- receiving a target image from a capture device;
- receiving a reference image;
- receiving a degradation parameter from an input device;
- based on an initial value of a feature point used for registration of an object included in the target image to be processed, generating feature point hypotheses that are groups of a plurality of the feature points in the target image;
- generating a degraded image by degrading the reference image, based on the feature point hypotheses and the degradation parameter;
- calculating a reliability of each feature point hypothesis, based on the target image, the degraded image, and each feature point hypothesis;
- selecting one of the feature point hypotheses by using the reliabilities, and executing registration of the target image and the degraded image by using the feature point included in the selected feature point hypothesis;
- and
- generating a restoration image associated with the target image, based on the registration of the target image.
