IMAGE PLUGINS FOR GIMP

GIMP
Image Plugins for GIMP
The GIMP is the acronym for GNU Image Manipulation Program.
It is a freely distributed piece of software suitable for such tasks as photo retouching, image composition and image authoring.
GIMP
Image Plugins for GIMP
GIMP uses external modules called plugins
Plugins can:– Load and save images– Run effects filters– Interface other programs with GIMP
• Scanning software• Ray tracer• Other image manipulation packages
GIMP
Image Plugins for GIMP
There are many things that can be accomplished with plugins
– Colouring Greyscale Images– Image Inpainting– Simulating Decorative Mosaics
GIMP
Colouring Greyscale Images
The inspiration for my first plugin comes from the paper “Transferring Color to Greyscale Images”
General technique for colouring greyscale images– Transfer colour between the source (colour
image) and the destination (greyscale image)
GIMP
Colouring Greyscale Images
Minimizes the human effort– Instead of choosing colours from RGB palette
the entire colour mood is transferred from the source to the destination
– This is done by matching the luminance and the texture information

Image Inpainting
The second plugin refers to the “Image Inpainting” paper
Image Inpainting is a technique used for modifying an image in an undetectable form.

The application of this plugin:
– Restoration of damaged paintings and photographs
– Removal of super imposed texts– Removal / replacement of selected objects

Simulating Decorative Mosaics
The last plugin that I will be attempting comes from the “Simulating Decorative Mosaics” paper.
Tile mosaics are images made up of small polygonal coloured patches
This method uses tiles to reproduce images
GIMP
Simulating Decorative Mosaics
The technique relies on the hardware to find analogous minimal-energy configurations to tile the mosaic.

Design and Implementation
GIMP - Linux– Use C to develop the plugins
GIMP is:– Open source– Well documented– A lot of reference material available– Easy to use
GIMP
Design and Implementation
GIMP interfaces with plugins
The position of the plugin is defined within itself– Example:
• (char *) "<Image>/Filters/Colors/ColourTransfer"
GIMP
Extensions
The method of colouring greyscale images can be extended to:
– Work on small images– Colour images with similar tones
GIMP
Extensions
Image inpainting can further be improved by:
– Improving the inpainting algorithm, allowing it to reproduce large textured regions.
GIMP
Extensions
Simulating decorative mosaics can be extended further by:
– Using higher order moments of each voronoi region
– Filling in gaps between tiles by using small tile chips
