Abstract
A method for increasing the confidence of a match between a test image and an image stored in a library database in which features are extracted from the test image and compared to features stored in the image database. If a match is determined, one or more transformations are performed on the test image to generate pose-altered images from which features are extracted and matched with pose-altered images in the database. The scores for the subsequent matchings can be aggregated to determine an overall probability of a match between the test image in an image in the library database.
Claims20
A method comprising:
- receiving a test image;
- extracting features from the test image;
- matching the features extracted from the test image with features stored in a library database;
- if a match is obtained, performing one or more transformations on the test image to generate one or more pose-altered images;
- extracting features from the one or more pose-altered images;
- and
- matching the features extracted from the one or more pose-altered images with features stored in the library database.
A system comprising:
- a processor;
- and
- software that, when excluded by the processor, causes the system to:
- receive a test image;
- extract features from the test image;
- match the features extracted from the test image with features stored in a library database;
- if a match is obtained, perform one or more transformations on the test image to generate one or more pose-altered images;
- extract features from the one or more pose-altered images;
- and
- match the features extracted from the one or more pose-altered images with features stored in the library database.
