Discriminatively Trained Sparse Code Gradients for Contour Detection
Xiaofeng Ren and Liefeng Bo

It contains visual comparisons of our sparse code gradients (SCG) vs Global Pb
(gPb) on the test set of the BSDS500 benchmark. As stated in the paper, the
three panels in the images are: (top) image, (middle) gPb contours; and
(bottom) SCG contours.

Please let us know ( xiaofeng.ren@intel.com ) if you have suggestions or
questions, or if you could make use of high-quality contours!
