IEEE Transactions on Pattern Analysis and Machine Intelligence, 2010
In this paper, we propose a novel explicit image filter called guided filter. Derived from a local linear model, the guided filter computes the filtering output by considering the content of a guidance image, which can be the input image itself or another different image.

Weighted Guided Image Filtering
IEEE Transactions on Image Processing, 2015It is known that local filtering-based edge preserving smoothing techniques suffer from halo artifacts. In this paper, a weighted guided image filter (WGIF) is introduced by incorporating an edge-aware weighting into an existing guided image filter (GIF) to address the problem.

Abstract This paper presents an improved version of the popular guided filtering (GF) technique. Although very effective, GF can suffer from artifacts such as edge blurring and halos. Through analyzing GF, we discover that traditional filtering practices of placing the center of the filtering window over the pixel being processed is one of the causes

Hyperspectral Pansharpening With Guided Filter
IEEE Geoscience and Remote Sensing Letters, 2017A new hyperspectral (HS) pansharpening method based on guided filter is proposed in this letter. The proposed method, which obtains the spatial detail difference of each band successively, is different from the traditional component substitution method. The detail information of each band is extracted at first.

Geotextile Filter Design Guide
Geotextiles and Geomembranes, 1992Abstract This paper provides the practicing designer with a comprehensive, systematic approach to solving common filtration design problems. Current filter design procedures often include only permeability and retention criteria. Several other concepts should be incorporated into the design process, such as: (i) consideration of whether permeability ...

Mutually Guided Image Filtering
Proceedings of the 25th ACM international conference on Multimedia, 2017Image filtering is helpful to numerous multimedia, computer vision and graphics tasks. Linear translation-invariant filters with manually designed kernels have been widely used. However, their performance suffers from the content-blindness, say identically treating noises, textures and structures. To mitigate the content-blindness, a family of filters,

Multichannel guided image filter
2017 IEEE International Conference on Image Processing (ICIP), 2017Guided image filter (GIF) is an edge-preserving filtering technique that smooths the fine texture of an input image with the guide of a second image. One shortcoming of GIF and all its existing variants, such as, weighed guided image filter and gradient domain guided image filter, is that they only use one grayscale image as the guide and are ...

Guided Filtering of Hyperspectral Images
2018 IEEE Winter Conference on Applications of Computer Vision (WACV), 2018Guided image filter (GIF) is an efficient edge-preserving image filter which has numerous applications in image processing. The filtered output of GIF is locally a linear transform of a guide image, which can be the input image itself or a different image. The key feature of GIF is that it does not suffer from gradient reversal artifacts.
