1. A method of generating an object descriptor, comprising: extracting, by a computer, gabor features from an input object image by applying a plurality of curvature gabor filters, generated via combination of a plurality of curvatures and a plurality of Gaussian magnitudes so that each curvature gabor filter of the plurality of curvature gabor filters has a different combination of curvature and Gaussian magnitude than the other curvature gabor filters of the plurality of curvature gabor filters, to the object image; and generating, by a computer, an object descriptor for object recognition by projecting the extracted features onto a predetermined base vector.
