A variety of methods for images noise reduction has been developed so far. Most of them successfully remove noise but their edge preserving capabilities are weak. Therefore bilateral image filter is helpful to deal with this problem. Nevertheless, their performances depend on spatial and photometric parameters which are chosen by user.

Gaussian-Adaptive Bilateral Filter
IEEE Signal Processing Letters, 2020Recent studies have demonstrated that a bilateral filter can increase the quality of edge-preserving image smoothing significantly. Different strategies or mechanisms have been used to eliminate the brute-force computation in bilateral filters. However, blindly decreasing the processing time of the bilateral filter cannot further ameliorate the ...

A bilateral filter in gradient domain
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012In this paper, a bilateral filter in gradient domain is first proposed. It is then applied to study detail enhancement via multi-light images and noise reduction of differently exposed low dynamic range images. These two applications show that the proposed filter can be applied to extract fine details from a set of images simultaneously and to provide ...

Edge-preserving smoothing is widely used in image processing and bilateral filtering is one way to achieve it. Bilateral filter is a nonlinear combination of domain and range filters. Implementing the classical bilateral filter is computationally intensive, owing to the nonlinearity of the range filter.

Content-Aware Bilateral Filtering
2018 IEEE Fourth International Conference on Multimedia Big Data (BigMM), 2018The edge-preserving bilateral filter (BF) has been widely used in real time applications (e.g., image denoising) for its low computational cost. The main drawback of BF lies in its sensitiveness to varying noise levels. To improve the robustness, non-local means (NLM) filter extends the pixel-based similarity distance to patch-based one.

Recursive Approximation of the Bilateral Filter
IEEE Transactions on Image Processing, 2015This paper presents a complete proof that the bilateral filter can be implemented recursively, as long as: 1) the spatial filter can be implemented recursively and 2) the range filter can be decomposed into a recursive product. As a result, an O(ND) solution can be obtained for bilateral filtering, where N is the image size and D is the dimensionality.

Bilateral filtering for video coding
2017 IEEE Visual Communications and Image Processing (VCIP), 2017This paper proposes the use of a bilateral filter as a coding tool for video compression. The filter is applied after transform and reconstruction, and the filtered result is used both for output as well as for spatial and temporal prediction. The implementation is based on a look-up table (LUT), making it fast enough to give a reasonable trade-off ...

Content adaptive bilateral filtering
2013 IEEE International Conference on Multimedia and Expo Workshops (ICMEW), 2013Bilateral filter is perhaps the most popular and simplest edge-preserving local filter. However, it may produce halos near some edges due to unwanted smoothing of the edges. In this paper, a content adaptive bilateral filter is proposed to overcome this problem.

Bilateral Filtering: Theory and Applications
Foundations and Trends® in Computer Graphics and Vision, 2009The bilateral filter is a non-linear technique that can blur an image while respecting strong edges. Its ability to decompose an image into different scales without causing haloes after modification has made it ubiquitous in computational photography applications such as tone mapping, style transfer, relighting, and denoising.

Bilateral Normal Filtering for Mesh Denoising
IEEE Transactions on Visualization and Computer Graphics, 2011Decoupling local geometric features from the spatial location of a mesh is crucial for feature-preserving mesh denoising. This paper focuses on first order features, i.e., facet normals, and presents a simple yet effective anisotropic mesh denoising framework via normal field denoising. Unlike previous denoising methods based on normal filtering, which
