Abstract:Almost all of existing works on structure-preserving texture smoothing utilize the statistical features of pixels within local rectangular patches to distinguish structures from textures.However,the patch sizes of the rectangular regions are single-scale,which may lead to texture over-smoothed or non-smoothed for images with sharp structures or structures at different scales.Thus,an adaptive scale bilateral texture filtering method was proposed.Firstly,the patch size of rectangular region for each pixel was chosen adaptively from some given candidate sizes based on statistical analysis of local patches,where larger patch sizes were chosen for the homogeneous texture regions and smaller ones for regions near the structure edges.Secondly,guided image were computed via the adaptive patch sizes.Finally,the guided bilateral filtering was operated on the original image.The experimental results demonstrate that the proposed method can better preserve image structures and smooth textures.
