Edge-aware smoothing

Edge-preserving smoothing or edge-preserving filtering is an image processing technique that smooths away noise or textures while retaining sharp edges. Examples are the median, bilateral, guided, anisotropic diffusion, and Kuwahara filters. See more In many applications, e.g., medical or satellite imaging, the edges are key features and thus must be preserved sharp and undistorted in smoothing/denoising. Edge-preserving filters are designed … See more Signal upsampling via the traditional interpolation followed by smoothing for denoising evidently distorts the edges in the original ideal or … See more • Edge detection See more Requirements of the strict edge preservation commonly limit the smoothing power of the filter, such that a single application of the … See more Anisotropic diffusion generates small conductance at the location of the edge of the image to prevent the heat flow over the edge, thus making the anisotropic diffusion filter edge-preserving. In the graph-based interpretation, the small conductance corresponds to a … See more WebAug 21, 2024 · Abstract: Edge-aware image smoothing plays an important part in practical applications of both computer vision and graphics.
