Robust Ear Recognition via Nonnegative Sparse Representation of Gabor Orientation Information
Figure 7
The process of Gabor orientation feature extraction from a randomly occluded test ear sample: (a) a 25% occluded test ear image from the first class of USTB ear database III. (b) Gabor filtering responses of the input ear sample; (c), (d), (e), and (f) present the Gabor orientation information across four different directions.
