METHOD FOR RECOGNIZING OBJECT USING COVARIANCE DESCRIPTOR AND APPARATUS THEREOF

摘要

Disclosed are object recognizing method and apparatus. The method may comprise extracting a feature point of an object to be recognized in an input image; generating a plurality of feature images by extracting orientation information of a region adjacent to the feature point and normalizing the region based in the orientation information; deriving a covariance descriptor based on the feature images; and recognizing the object in the input image by comparing the covariance descriptor with a reference covariance descriptor stored in advance. Thus, the object can be recognized fast and robustly to changes on the size of the input image, rotations of the input image, and illumination, whereby the recognition performance can be enhanced.

1. A method for recognizing objects, performed in an information processing apparatus which can perform digital signal processing, the method comprising:
extracting a feature point of an object to be recognized in an input image; generating a plurality of feature images by extracting orientation information of a region adjacent to the feature point and normalizing the region based on the orientation information; deriving a covariance descriptor based on the plurality of feature images; and recognizing the object in the input image by comparing the covariance descriptor with at least one reference covariance descriptor stored in advance.
