G'MIC plug-in

dtschump — Tue, 13 Jan 2009 14:16:31 +0100

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

This plug-in is able to update his list of filter definitions from the Internet (so it improves itself over time), as well as allows any user to add its own custom filters in it.
It has been written by the author of the GREYCstoration algorithm (used for image denoising). It is actually intended to replace it in a near future.

Here is one screenshot of the plug-in in action, as well as a result of filter application :

Lomo-Gimp

ivalladt — Thu, 14 Aug 2008 13:06:35 +0200

Lomo-Gimp tries to give your digital pictures the warmth of those taken by an old rangefinder analog camera. Think of it as a Kodak Instamatic or a Lomo Holga faking effect. It enhances contrast and saturation, and applies a light and a dark overlay, trying to emulate incorrectness in exposition. Please note this does nothing to emulate the chromatic aberration peculiar in pictures taken using a real Lomo.

Get it at Lomo-Gimp.

Pseudo Tone Fixer

sentinel1977 — Mon, 11 Feb 2008 15:26:03 +0100

This script tries to fix the tone of a photo taken with wrong exposure. In some landscape photos, it can have a nice effect of enhancing the colors.

The general idea is to produce different copies of the image at different gamma levels, then applying simple tone mapping techniques to produce a vibrant photo.

The script allows the user to control the number of copies by setting the lowest and highest gamma setting then the interval. For example lowest=20, highest=170, interval=10 results to (170-20)/10 = 15 copies with increasing gamma level from 0.2 to 1.7. Play around!

This is my first script and not so optimized, anyone is welcome to improve on it.
Warning, the higher the number of copies, the slower it becomes, especially on photos above 640x480. Best to try on reduced copies first.

Liquid Rescale

carlobaldassi — Sun, 13 Jan 2008 22:06:31 +0100

This plugin aims at resizing pictures non uniformly while preserving their features, i.e. avoiding distortion of the important parts.

For example, you may turn a normal picture to panoramic without stretching the content.

The plugin supports manual feature selection, and can also be used to remove portions of the picture in a consistent way.

More information:

Official Liquid Rescale homepage (binary packages, examples, tutorials etc.)
The plugin is a frontend to the Liquid Rescale Library
The library implements the Seam Carving algortihm as described in this paper and shown in this video by Shai Avidan and Ariel Shamir.
