  1. IMAGE PLUGINS FOR GIMP By: Vera Kukić Supervisors: Shaun Bangay and Adele Lobb GIMP

  2. 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

  3. 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

  4. Image Plugins for GIMP • There are many things that can be accomplished with plugins • Colouring Greyscale Images • Image Inpainting • Simulating Decorative Mosaics GIMP

  5. 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

  6. 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 GIMP

  7. Colouring Greyscale Images GIMP

  8. Colouring Greyscale Images GIMP

  9. 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. GIMP

  10. Image Inpainting • The application of this plugin: • Restoration of damaged paintings and photographs • Removal of super imposed texts • Removal / replacement of selected objects GIMP

  11. Image Inpainting GIMP

  13. Image Inpainting GIMP

  14. 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

  15. Simulating Decorative Mosaics • The technique relies on the hardware to find analogous minimal-energy configurations to tile the mosaic. GIMP

  20. 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

  21. Design and Implementation • GIMP interfaces with plugins • The position of the plugin is defined within itself • Example: • (char *) "<Image>/Filters/Colors/ColourTransfer" GIMP

  22. Extensions • The method of colouring greyscale images can be extended to: • Work on small images • Colour images with similar tones GIMP

  23. Extensions • Image inpainting can further be improved by: • Improving the inpainting algorithm, allowing it to reproduce large textured regions. GIMP

  24. 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 GIMP
