Abstract
The apparatus includes: a weighted feature extractor configured to extract a weighted feature from an input image and generate a weighted descriptor to which a feature of a salient region is applied; a dictionary constructor configured to construct a dictionary composed of images with different characteristics of one object using the weighted descriptor to which the feature of the salient region is applied by the weighted feature extractor and store the dictionary in a database (DB); and a coefficient estimator and ID determiner configured to apply sparse representation for estimating a coefficient that allows an object to be reconstructed as much as possible with a few linear combinations of candidate objects of a target object constituting the dictionary, and perform identification using an error between a target and the reconstructed object.
