Robust Ear Recognition via Nonnegative Sparse Representation of Gabor Orientation Information
Orientation information is critical to the accuracy of ear recognition systems. In this paper, a new feature extraction approach is investigated for ear recognition by using orientation information of Gabor wavelets. The proposed Gabor orientation feature can not only avoid too much redundancy in co...
