BayerDithering

This repository provides source code to quantize and dither an image using the Bayer matrix. The code supports both greyscale and RGB images.

Usage

Compile the code and run it by specifying the number of colors you want per channel, and the path to the image. For example, the following command loads the image example/ramp.png and quantifies it using 3 colors

./dither 3 example/ramp.png

Here is the input and output for this particular example:

Note that the program will systematically export the dithered result to the .BMP file output.bmp.
