Abstract We presented a weighted SRC (Sparse Representation-based
Classification) algorithm for recognizing face images under the
condition of illumination and expression as well as disguise.
Firstly, we established a weighted model, and then different sparse
solutions were acquired by Homotopy method under the different
weight values. The ideal weight value was obtained by computing the
minimal residual. Finally, we got the sufficiently sparse solution
and made discriminant. Experimental results based on the AR database
show that the weighted SRC algorithm can get sparser solution and
higher recognition rate than SRC for disguise face recognition. In
addition, we notice that it has very good effect to recognize
low-dimensional and disguise face image in the application of small
scale.
