The guided bilateral filter
A bilateral filter is a non-linear, edge-preserving, and noise-reducing smoothing filter for images. It replaces the intensity of each pixel with a weighted average of intensity values from nearby pixels. This weight can be based on a Gaussian distribution. Crucially, the weights depend not only on Euclidean distance of … See more The bilateral filter is defined as $${\displaystyle I^{\text{filtered}}(x)={\frac {1}{W_{p}}}\sum _{x_{i}\in \Omega }I(x_{i})f_{r}(\ I(x_{i})-I(x)\ )g_{s}(\ x_{i}-x\ ),}$$ and normalization … See more • As the range parameter σr increases, the bilateral filter gradually approaches Gaussian convolution more closely because the range Gaussian widens and flattens, which means that it becomes nearly constant over the intensity interval of the image. See more Adobe Photoshop implements a bilateral filter in its surface blur tool. GIMP implements a bilateral filter in its Filters → Blur tools; and it is called Selective Gaussian Blur. The free G'MIC plugin Repair → Smooth [bilateral] for GIMP adds more control. A simple … See more • Kaiming He: Guided image filtering (faster than bilateral filter and avoids staircasing and gradient reversal artifacts) • Haarith Devarajan, Harold … See more The bilateral filter in its direct form can introduce several types of image artifacts: • Staircase effect – intensity plateaus that lead to images appearing like cartoons • Gradient reversal – introduction of false edges in the image. See more The bilateral filter has been shown to be an application of the short time kernel of the Beltrami flow that was introduced as an edge preserving selective smoothing mechanism before … See more • Gaussian filter • Gaussian function • Gaussian blur See more Web1 Jun 2013 · The guided filter is also a more generic concept beyond smoothing: It can transfer the structures of the guidance image to the filtering output, enabling new filtering …

WebThe bilateral filter (BF) is a non-linear filter that spatially smooths images with awareness of large structures such as edges. The level of smoothness applied to a pixel is constrained by a photometric weight, which can be obtained from the same image to be filtered (in case of the original BF) or from a guided image (in case of the joint/cross BF).
