guidedfiltering

2021年12月22日 — A guided filter is used in digital image restoration by removing noise from the image. Guided filters are used with colour images also. In the ...

A guided filter is an edge-preserving smoothing image filter. As with a bilateral filter, it can filter out noise or texture while retaining sharp edges.

This MATLAB function filters binary, grayscale, or RGB image A using a filter guided by image G.

The guided filter can be used as an edge-preserving smoothing operator like the popular bilateral filter, but has better behaviors near edges. The guided filter ...

Guided image filtering uses context from a separate image, known as a guidance image, to influence the output of image filtering. Like other filtering ...

2019年5月5日 — 引导图滤波器是一种自适应权重滤波器，能够在平滑图像的同时起到保持边界的作用。

如果方差大，即是边缘的话，ak 就约等于1 （epsilon很小），因此，b 就约等于0。相当于输出等于输入只是乘以一个约等于1的系数，这样可以保证梯度的比例关系不变。

2019年10月15日 — 導向濾波由於整個流程都是線性的，所以甚至在深度學習中可以作為一個層(layer)使用，並求出梯度進而反向傳播(Back Propagation)。
