filter

A surface blur filter based on a simplified version Porikli's O(1) bilateral filter.

Unfortunately due to the nature of the algorithm memory overheads can be severe. This filter uses a tile based implementation, which limits overheads to about 64mb.

On the plus side it is reasonably fast and scales well with filter radius.

When installed it should appear under filters->blur->simple bilateral

There is a mercurial repository which will be kept up to date with the latest code on my web site. This can be accessed with:

hg clone http://www.spectral3d.co.uk/repo/gimp_plugins

What is Color Spotter? Basically, it's contrast, but "centered" around a color. Another way to see it is as another "Color selection" tool: you specify an image, a kind of threshold, and it selects color that are close to the one you specified; only, Color Spotter keeps every pixel from the image, darkening the wanted colors, brightening the others.

The G'MIC plug-in for GIMP proposes a set of various filters to apply on your images, including artistic effects, image denoising and enhancement algorithms, 3D renderers, etc.. It is a quite large plug-in, integrating a lot of different effects.

The code still have some accuracy bugs when compaired with its sdlBasic version, since i were getting some problems when recoding it to Python-Gimp.
The script converts a rgb picture into msx1 (also colecovision and sega sg1000) display limitations, which have a predefined palette, and a maximum of 2 colours in each 8x1 pixels cell, trying to provide this cell as the most close as possible from their rgb original.
As well, the code is a bit slow (a 320x240 picture can take around 1 minute on a 2ghz dualcore computer) since it processes pixel by pixel.
