Bilateral texture filtering [PDF]
ACM Transactions on Graphics, 2014 This paper presents a novel structure-preserving image decomposition operator called bilateral texture filter . As a simple modification of the original bilateral filter [Tomasi and Manduchi 1998], it performs local patch-based analysis of texture features and incorporates its results into the range filter kernel ...

A New Hybridization of Bilateral and Wavelet Filters for Noisy De-Noisy Images
Eurasian Journal of Science and Engineering, 2023 In this work we propose, a hybrid noise reduction algorithm that is a combination of a spatial field binary filter and a hybrid wave field threshold function. These two methods are used to stop Gaussian noise. The hybrid filter is a nonlinear filter that

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.

Contrast Sensitivity Based Multiscale Base–Detail Separation for Enhanced HDR Imaging
Applied Sciences, 2020 High dynamic range (HDR) imaging is used to represent scenes with a greater dynamic range of luminance on a standard dynamic range display. Usually, HDR images are synthesized through base–detail separations.

Near-Infrared Image Colorization Using Asymmetric Codec and Pixel-Level Fusion
Applied Sciences, 2022 This paper mainly studies the colorization of near-infrared (NIR) images. Image colorization methods cannot be extended to NIR image colorization since the wavelength band of the NIR image exceeds the visible light spectral range and it is often linearly

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.

The Bilateral Filter for Point Clouds [PDF]
Image Processing On Line, 2017 Point sets obtained by 3D scanners are often corrupted with noise, that can have several causes, such as a tangential acquisition direction, changing environmental lights or a reflective object material. It is thus crucial to design efficient tools to remove noise from the acquired data without removing important information such as sharp edges or ...
