获得平滑纹理和保持边缘的滤波输出对图像分解具有重要意义。虽然边缘和纹理在人类视觉中具有显著的差异，但由于它们具有相似的强度差异或梯度响应，因此自动区分它们是一项困难的任务。目前基于边缘保持平滑（EPS）的分解方法很难得到满意的结果。提出了一种新的边缘保持纹理抑制滤波器，利用联合双边滤波器作为桥梁，实现了纹理平滑和边缘保持的双重目的。采用迭代非对称采样和局部线性模型生成退化图像来抑制纹理，并应用边缘校正算子实现边缘保持。为了提高滤波响应的性能，引入了一种有效的加速实现。实验结果表明，该滤波器具有良好的纹理平滑和边缘保持性能，并在信号分析、视觉分析和时间分析方面与其他常用的EPS方法进行了比较。最后，我们将滤波器扩展到各种图像处理应用中。
Obtaining a texture-smoothing and edge-preserving filtered output is significant to image decomposition. Although the edge and the texture have salient difference in human vision, automatically distinguishing them is a difficult task, for they have similar intensity difference or gradient response. The state-of-the-art edge-preserving smoothing (EPS) based decomposition approaches are hard to obtain a satisfactory result. We propose a novel edge-preserving texture suppression filter, exploiting the joint bilateral filter as a bridge to achieve the purpose of both properties of texture-smoothing and edge-preserving. We develop the iterative asymmetric sampling and the local linear model to produce the degenerative image to suppress the texture, and apply the edge correction operator to achieve edge-preserving. An efficient accelerating implementation is introduced to improve the performance of filtering response. The experiments demonstrate that our filter produces satisfactory outputs with both properties of texture-smoothing and edge-preserving, while compared with the results of other popular EPS approaches in signal, visual and time analysis. Finally, we extend our filter to a variety of image processing applications.
