Anaglyph to Stereo Pair (cross-eye)

There were a few anaglyph 3D images that I wanted to view as cross-eyed stereo pairs (I don't have glasses handy). I started doing the manipulations by hand to convert them from anaglyphs, then got tired of doing it manually.

So, I wrote a quick script-fu to do it for me. This will take a 3D Anaglyph image (red/cyan), and create a stereo pair (monochrome) for you...

Just load up an image, and run:

Filters > Generic > Anaglyph to Stereo...

Color Decompose (For B&W Conversions)

As part of writing the next part of my tutorials on B&W conversion, I needed to quickly decompose an RGB image into different grayscale channels based on useful channels from all the color modes (RGB, CMY(K), LAB, HSV, HSL, YCbCr).

It was tedious doing it by hand, so I wrote up this small script to automatically decompose an RGB image layer (active) into each of the color decomposition modes, and to keep the most useful to me for B&W conversions.

Drag mouse to resize brush (updated for linux)

Works like the blender brush size controls, making it easy to change your brush size with a mouse or graphics tablet by letting you drag the mouse left to right to interactively change the brush size.

Now you don't have to tap hotkeys repeatedly or interrupt your painting flow by moving the mouse to the slider

Requirements
---------------------------
Gimp 2.8
Windows (tested on Windows 7 x64)
Linux (tested on Ubuntu 12.04 x64)

BgMask: extract still background from video frames / mask frames against background

May 21, 2013: BgMask 0.3 is released!

Video tutorial: http://www.youtube.com/watch?v=h7uJUiyJ1yw

This script adds several tools under Script-Fu - BgMask: "Extract background...", "Mask against background...", "Average linked layers...", and in BgMask 0.2 there are also "Extract background manually" and "Mask adjustments...". It can be used to mask moving objects/characters from animations with still background.

BgMask 0.3 introduces a new tool, "Blend Edges" which allows your masked objects to blend seamlessly into different backgrounds. Also, it improves the denoising algorithm of Mask Adjustments and adds a "Smoothen via paths" option.

Read the full description for detailed breakdown.

MagicLantern compatible YUV422 raw file (.422) Loader/Saver

This plug-in implements load and save of MagicLantern compatible YUV422 raw files.
MagicLantern is a free software add-on for Canon EOS cameras. This software
can take "silent pictures" as snapshot of the Camera Display
and saves them as uncompressed raw YUV422 files with extension .422.

The silent picture feature is useful to record timelapse sequences without moving the mirror
of the camera.
If you want to process such sequences of .422 images with GIMP (or GIMP-GAP) you should install
this file-raw-yuv422 plug-in.
