A Fast Iterative Pursuit Algorithm in Robust Face Recognition Based on Sparse Representation
Figure 1
(a) is an input sample with contiguous occlusion. (b) is the sparse solution based on the OMP algorithm. (c) is the reconstructed image, whose class is the same as the class of the largest entry of the sparse solution. Obviously, the solution is not sparse enough and we have got a wrong answer due to the occluded part in .
