This program abstracts images by removing details from them and makes them cartoon-like. It is based on the paper Stylization and Abstraction of Photographs (SIGGRAPH 2002), by DeCarlo and Santella.
main (image_name, num_colors)
num_colors specifies number of colors in the output image. Smaller this value, more abstraction happens in the output image.
Example:
main ('scarlet.jpg', 20)
