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 (

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 ...

Constant Time Joint Bilateral Filtering Using Joint Integral Histograms
IEEE Transactions on Image Processing, 2012 In this brief, we present a constant time method for the joint bilateral filtering. First, we propose an image data structure, coined as joint integral histograms (JIHs).

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 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 ...

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.

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 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 Filtered Shadow Maps
2009We present a novel shadow smoothing algorithm using the bilateral filter. From the observation that shadow leaking, which is found often in filter based approaches, occurs at depth discontinuity seen from the viewpoint of the eye, we apply the bilateral filter which is conceptually a product of two Gaussian filters, one for smoothing the shadow map and
