= Image Labs
A collection of image processing experiments done in Ruby.
== /bin/rmagicksh ==
This is a script to launch irb w/ all the image_labs libraries as well as some convenience functions included.
== SeamCarver
Includes code to do edge detection (with the Prewitt kernel), energy mapping, and seam carving. Located in /lib/seamcarver
== Blender
Includes code to do image blending a la photoshop's blending layers. Located in /lib/blender
== Mosaicer/PhotoMosaicer
Includes code to generate large photomosaics and tiled mosaics (using the RMagick #mosaic function) of thumbnails.
== Evolution
Includes code that implements a darwinian-style genetic algorithm to "evolve" images out of a random collection of polygons. This code currently is too slow and often gets stuck in local minima.
== Facer
Interface to the ruby-opencv gem (see http://github.com/bantic/ruby-opencv for more info and installation instructions) to do face detection. Has opencv gem as a dependency. If you're using /bin/rmagicksh, type '$ load_facer' to load this gem and the Facer class.
== Spec
There is moderate test coverage in /spec. Run the tests with $ spec spec/*
== Fixtures and Images
/fixtures includes image data used by the tests, and /images includes sample images to play with the code.
