局部滤波方法:双边滤波(Bilareral Filter)、三边滤波(Trilateral Filter)、引导滤波(Guided Image Filter)等。 局部滤波实现简单,但是对边缘锐度的保持性不如全局滤波,而且被用于平滑图像时,会产生光晕(halos)。 2 局部边缘保持滤波原理 将图像分解成两部分 :X(p) = Z(p) + e(p) = 基础层+细节层 ——Z是...
Proposed weighted guided image filter algorithm improves the quality of an image and by the use of haze removal algorithm a high quality depth map can also be obtained.doi:10.1016/j.protcy.2016.05.248H. GeethuS. ShamnaJubilant J. Kizhakkethottam...
We present a weighted guided image filter (WGIF) to improve filtering and avoid halo artifacts. We know that the previously used local filtering-based edge preserving smoothening technique suffers from halo artifacts and also some drawbacks. To overcome this problem we are introducing an extension ...
In this paper, a weighted guided image filter (WGIF) is introduced by incorporating an edge-aware weighting into an existing guided image filter (GIF) to address the problem. The WGIF inherits advantages of both global and local smoothing filters in the sense that 1) the complexity of the ...

An underwater image enhancement technique based on weighted guided filter image fusion is proposed to address challenges, including optical absorption and scattering, color distortion, and uneven illumination. The method consists of three stages: color correction, local contrast enhancement, and fusion alg...
Firstly, a weighted median filter is convoluted with an input rainy image to obtain a coarse rain-free image; then, guided filter is employed to obtain a refined rain-free image, where the coarse rain-free image is used as a guided image and convoluted with the input rainy image via ...
