Image Filterer

A collection of image filters.

Filters

• Color Difference Filter - recursively pixelate similar areas based upon similarity of color

• Luminosity Difference Filter - same as color difference filter, but using luminosity

• Pixelating Filter - simply pixelates the image

• Polygon Filter - randomly placed polygons (only pentagons currently)

• Triangle Filter - evenly spaced regular triangles

• Stipling Filter - a bunch of dots (evenly sized) randomly placed based on luminosity

• Blur Filter - blurs by getting average color in radius around each pixel

• Recursive Square Filter - like color difference filter, but choice to recurse is taken randomly

• Pixel Map Filter - basically the same as the blur filter AFAIK

• Affine Transform Filter - change angle (rotation), sheer, and scale

• Brightness Contrast Filter - change brightness and contrast

Additional work / notes

• All processing is done on the CPU, and is single threaded which makes it pretty slow.

• Can only use one filter at once. Using multiple filters in succession would be nice.
