Color Image Compression by using Walsh and Wavelet Transform (WWT):
This
project depends on Wavelet and Walsh transform for transformation, and then
using Arithmetic coding for compress an image.
Compression algorithm consists of the
following steps:
A)
Two Levels Discrete Wavelet Transform
B)
Apply 2D Walsh-Hadamard Transform on each 8x8 block of the low-frequency sub-band
C)
Split all DC values form each transformed block 8x8
D)
Compress each sub-band by using Arithmetic coding
