A C++ program that turns an image into a toon that can be painted using a color palette.
The algorithm is based on the paper Toonify: Cartoon Photo Effect Application.
After installation of opencv via
brew install opencv
compile the C++ program toonify.cpp with
make
Usage
./toonify [path_to_file] [num_colors] [blur_level] [scale_factor]
Number of colors and blur level control the resolution of the toonified image. For example, the number of colors should be 16 or 20 for a nice effect. The blur level should be 11, 17, or higher for larger images (it must be an odd integer number). A scale factor of x means that the image will be x times larger than the original (use with caution!).
