Color Image Compression Using Polynomial and Quadtree Coding Techniques
Ban Nadeem Dhannoon, Loay Edwar George · 2013
The aim of this research is to introduce a simple and fast hybrid image color which implies polynomial image technique and quadtree coding. Image blocks are approximated by polynomial functions, and the residue image signal is coded by a hierarchal quantization scheme followed by quadtree coding. Quadtree is applied to encode the nearly sparse blocks of quantized residue signal. The conducted tests of this proposed color image coding scheme have shown encouraging compression performance (in compression with other existing coding schemes). In addition to the good performance aspects the scheme is simple and fast.
