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.

Luminosity Masks

Tony Kuyper describes a great way to manage tones in Photoshop that he calls "Luminosity Masks." See http://goodlight.us/writing/luminositymasks/luminositymasks-1.html for his thorough description of how they work and what they can do. I have implemented and extended them in this Gimp plugin.

Installation:
Put gimp-luminosity-mask.py in your Gimp plugins directory. Usually this is ~/.gimp-2.x/plug-ins. Restart Gimp.

Usage:

GIMP Mask

GIMP Mask can do and undo several popular image masking (that is, censoring) methods (CP, FL, Q0, MEKO). It was originally written in 1998 by Hirotsuna Mizuno and is now updated to work with GIMP 2.x.

Range Selection Script

The range selection script is a tool for easy and automatic creation of selections and lay­er masks. The selections or masks include all parts of the image that are situated within a defined range of tonal values, colours, saturation or edges. Selections can be based on one of 16 channels. For detailed instructions and several samples have a look at the attached manual.

Mask Copier

Apply other layers masks. Copy mask in active layer to all other layers.

This script is created by Joao S. O. Bueno at my request and I take no credit for it's development.

Appears in /Layer/Transparency/Copy Mask to Other layers of the Image window.

Merge Visible with Layer Mask & Alpha

Merge visible using the active layer transparency to create a mask, visible layers below are discarded.

This can be useful in 3d applications to preserve texture maps that belong in the alpha channel by using the bottom layer's mask to hold the information.

Appears in /Image/Merge Visible with Layer Mask & Alpha of the Image window.
