1. A method comprising: under control of one or more processors configured with executable instructions, determining a first pose category of at least a portion of a first image from among a plurality of pose categories; transforming at least the portion of the first image to a second pose category corresponding to a second image to obtain a transformed image, wherein at least a portion of the transformed image is divided into a plurality of cells; using multiple descriptors to extract features for each cell of the portion of the transformed image; rescaling the results of the multiple descriptors determined for each cell; concatenating the rescaled results to obtain a combined feature vector for each cell of the plurality of cells; compressing the combined feature vectors to obtain a compact final descriptor representative of at least the portion of the transformed image; and comparing the transformed image with the second image to determine, at least in part, whether the first image is a match with the second image.
