Bilateral Filter Line
Filter the image using bilateral filtering.
Bilateral filter line. This weight can be based on a gaussian distribution. If you have multiple images to filter with the same guide then use fastbilateralsolverfilter interface to avoid extra computations. Imshow j title degree of smoothing. Summary the bilateral filter is ubiquitous in computational photography applications.

The bilateral filter is perhaps the simplest and most intuitive one among explicit weighted average filters. Set the degree of smoothing to be larger than the variance of the noise.
However these convolutions often result in a loss of important edge information since they blur out everything irrespective of it being noise or an edge. Simple one line fast bilateral solver filter call. It is increasingly common in computer graphics research papers but no single reference summarizes its properties and applications. The bilateral filter smooths the image while preserving edges.
A bilateral filter is used for smoothening images and reducing noise while preserving edges. A bilateral filter is a non linear edge preserving and noise reducing smoothing filter for images it replaces the intensity of each pixel with a weighted average of intensity values from nearby pixels. Following is the syntax of this method. Bilateral filter crosses thin lines bilateral filter averages across features thinner than 2σ s desirable for smoothing.
This article explains an approach using the averaging filter while this article provides one using a median filter. Bilateralfilter src dst d sigmacolor sigmaspace bordertype. You can perform this operation on an image using the medianblur method of the imgprocclass. More pixels more robust different from diffusion that stops at thin lines close up kernel.
