Edge-Aware Filter Based on Adaptive Patch Variance Weighted Average
IEEE Access, 2021 Edge-aware smoothing is an essential tool for computer vision, graphics and photography. In this paper, we develop a new and efficient local weighted average filter for edge-aware smoothing.

Fast Gauss Bilateral Filtering [PDF]
Computer Graphics Forum, 2010 Abstract In spite of high computational complexity, the bilateral filter and its modifications and extensions have recently become very popular image and shape processing tools. In this paper, we propose a fast and accurate approximation of the bilateral filter. Our approach combines a dimension elevation trick with a Fast Gauss Transform.

Adaptive Bilateral Texture Filter for Image Smoothing
Frontiers in Neurorobotics, 2022 The biggest challenge of texture filtering is to smooth the strong gradient textures while maintaining the weak structures, which is difficult to achieve with current methods. Based on this, we propose a scale-adaptive texture filtering algorithm in this

Morphological Bilateral Filtering [PDF]
SIAM Journal on Imaging Sciences, 2013 Summary: A current challenging topic in mathematical morphology is the construction of locally adaptive operators, i.e., structuring functions that are dependent on the input image itself at each position. Development of spatially variant filtering is well established in the theory and practice of Gaussian filtering.

Bilateral filter in image processing [PDF]
, 2009 The bilateral filter is a nonlinear filter that does spatial averaging without smoothing edges. It has shown to be an effective image denoising technique. It also can be applied to the blocking artifacts reduction. An important issue with the application

Impact of Iterative Bilateral Filtering on the Noise Power Spectrum of Computed Tomography Images
Algorithms, 2022 A bilateral filter is a non-linear denoising algorithm that can reduce noise while preserving the edges. This study explores the characteristics of a bilateral filter in changing the noise and texture within computed tomography (CT) images in an ...

Shot-noise adaptive bilateral filter [PDF]
, 2008 electronic version (4 pp.)International audienceThe bilateral filter (BF) is an important image denoising local filter. It reduces noise in images while preserving edges by means of nonlinear combination of local pixel values.

BILATERAL FILTER: GRAPH SPECTRAL INTERPRETATION AND EXTENSIONS [PDF]
, 2013 In this paper we study the bilateral filter proposed by Tomasi and Manduchi and show that it can be viewed as a spectral domain trans-form defined on a weighted graph.
