A weighted discriminative approach for image denoising with overcomplete representations

13 years 5 months ago

Download www.cs.technion.ac.il

We present a novel weighted approach for shrinkage functions learning in image denoising. The proposed approach optimizes the shape of the shrinkage functions and maximizes denois...
