The paper presents a new graph-based implementation of bilateral filtering. Based on the Laplacian mesh smoothing framework, the proposed filter mimics the behaviour of the classical mesh filter while retaining some of the interesting properties of mesh smoothing. The comparison between the filters is twofold.

Compressive Adaptive Bilateral Filtering
ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020We propose a fast algorithm for an adaptive variant of the classical bilateral filter, where the range kernel is allowed to vary from pixel to pixel. Several fast and accurate algorithms have been proposed for bilateral filtering, but they assume that the same range kernel is used at each pixel and hence cannot be used for adaptive bilateral filtering (

Compressive Bilateral Filtering
IEEE Transactions on Image Processing, 2015This paper presents an efficient constant-time bilateral filter that produces a near-optimal performance tradeoff between approximate accuracy and computational complexity without any complicated parameter adjustment, called a compressive bilateral filter (CBLF).

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.

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.

Bilateral Filtering of fMRI Data
IEEE Journal of Selected Topics in Signal Processing, 2008We present a class of adaptive filtering techniques of functional magnetic resonance imaging (fMRI) data related to bilateral filtering. This class of methods average activities in consistent regions rather than regions that maximize correlation with a BOLD model.

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.
