Abstract
We present here a sparse coding algorithm dedicated exclusively to overcomplete Gabor wavelets and based on perceptual contour extraction methods. The algorithm has reduced computational cost and achieves compression rates similar to the standard image compression algorithms (JPEG and JPEG-2000) with the additional advantage of limiting the appearance of artifacts.
