Based on this definition, we propose an edge-preserving image smoothing algorithm. Firstly local extrema of the input image are located. Then these extrema points are classified into edge or detail points by the two properties. Thirdly, max and min envelops are obtained by an optimizing process...
We present a new edge-preserving image smoothing approach by incorporating local features into a holistic optimization framework. Our method embodies a gradient constraint to enforce detail eliminating and an intensity constraint to achieve shape maintaining. The gradients of high-contrast details are supp...
However, they also tend to suppress high-rate intensity variations that are part of the original signal, thereby destroying image structures that are visually important. The filters described in this chapter are "edge preserving" in the sense that they change their smoothing behavior adaptively ...
Image smooth plays an important role in image pre-processing. For classical image smoothing models, a convex total variation regularizer or a nonconvex regularizer has been widely used to protect image edges and to smooth noise. In this paper, we propose a new effective model in which the tota...
Edge-avoiding wavelets with explicit image-adaptive weights can also be used for edge-preserving image smoothing [7]. However, constraints on kernel size of the wavelet may limit its applicability. Derived from a local linear model between a guidance image and the final filtering result, explicit...

In this paper, we propose least-squares images(LS-images) as a basis for a novel edgepreserving image smoothing method. The LS-image requires the value of each pixel to be a convex linear combination of its neighbors, i.e., to have zero Laplacian, and to approximate the original image ...
