摘要：

A new method for automatic enhancement of noisy images is presented. The most relevant feature of the proposed approach is a novel procedure for automatic parameter tuning that takes into account the histograms of the edge gradients. Thus a satisfactory compromise between smoothing and sharpening can be automatically found according to the human perception. The proposed method is favorably compared to other techniques in the literature.
