Currently, mobile image applications spend a lot of computing process to display images. A true color raw image
contains billions of colors and it consumes high computational power in most mobile image applications. At the same
time, mobile devices are only expected to be equipped with lower computing process and minimum storage space. Image
dithering is a popular technique to reduce the numbers of bit per pixel at the expense of lower quality image displays.
This paper proposes a novel approach on image dithering using 2x2 Tchebichef moment transform (TMT). TMT
integrates a simple mathematical framework technique using matrices. TMT coefficients consist of real rational numbers.
An image dithering based on TMT has the potential to provide better efficiency and simplicity. The preliminary
experiment shows a promising result in term of error reconstructions and image visual textures.
