Anisotropic filtering improves the clarity and crispness of textured objects in games. Textures are images containing various types of data such as color, transparency, reflectivity, and bumps (normals) that are mapped to an object and processed by the GPU. Anisotropic filtering algorithm was proposed, which can filter out the background noise while preserve object boundary effectively. The filtering performance was evaluated by comparing that with some other filtering algorithms. In anisotropic implementations, the filtering may incorporate the same filtering algorithms used to filter the square maps of traditional mipmapping during the construction of the intermediate or final result.

Aug 05, 2017 Anisotropic filtering is commonly abbreviated as 'AF' in game menus. It’s one of the settings we'd recommend you prioritize cranking up, but this one’s a little tricky to dissect, so here’s. The texture filtering hardware takes several samples of the various mipmap levels (the maximum amount of samples is indicated by the anisotropic filtering level, though the exact amount of samples taken in a given filtering operation will depend on the proportion between the derivatives on the fragment.) If you project.
I want to use anisotropic diffusion on 2d images.
I'd like to use python but don't mind using matlab or c. Are their any libraries I could use as a first step? I did a google search on the subject and found Panda3D and OpenGl.
Basically I want to give a set of images have it apply the filtering and then output the new image to a folder I want.
Any tips on how to use either of these or maybe something that you believe is better?
edit: Meant diffusion sorry!

Here's my Python/numpy implementation of 2D and 3D anisotropic (Perona-Malik) diffusion. It's not quite as fast as C-code, but it did the job nicely for me.

You don't mean Anisotropic diffusion? C is probably the best(faster then matlab and python). But there is a toolbox for image analysis in matlab: matlabimagetoolbox. I made a program for doing isotropic diffusion in c, the only lib I used was libjpeg for importing and exporting the images.
