Abstract
At least one example embodiment discloses a method of extracting a feature of an input image. The method includes constructing an example pyramid including at least one hierarchical level based on stored example images, generating a codebook in each of the at least one hierarchical level, calculating a similarity between the codebook and the input image, and extracting a feature of the input image based on the similarity.
Claims20
A method of extracting a feature of an input image, the method comprising:
- constructing a example pyramid including at least one hierarchical level based on stored example images;
- generating a codebook in each of the at least one hierarchical level;
- calculating a similarity between the codebook and the input image;
- and
- extracting a feature of the input image based on the similarity.

A facial recognition apparatus comprising:
- a face extractor configured to extract a facial area from an input image;
- a normalizer configured to perform normalization on the facial area;
- a feature extractor configured to extract a feature of the input image based on the normalized facial area and a stored codebook;
- and
- a recognizer configured to recognize a face based on the extracted feature,
- wherein the codebook is based on example image groups in each level of a example pyramid using stored example images.
