Nonlinear kernel based feature maps for blur‐sensitive unsharp masking of JPEG images
Abstract In this paper, a method for estimating the blur regions of an image is first proposed, resorting to a mixture of linear and nonlinear convolutional kernels. The blur map obtained is then utilized to enhance images such that the enhancement strength is an inverse function of the amount of me...
