Robust Ear Recognition via Nonnegative Sparse Representation of Gabor Orientation Information

Figure 8

Sparse coding coefficients and representation residual of the 25% occluded test ear image from the first class of USTB; (a) and (c) plot the coding coefficients of Gabor orientation + SRC and Gabor orientation + NSRC. (b) and (d) illustrate the representation residual associated with each class by Gabor orientation + SRC and Gabor orientation + SRC, respectively.
