Wavelet Based Image Compression implementation using SOFM

19 Oct 2005 (Updated 10 Apr 2006)

Generating Adaptive Codebook using SOFM.

File Information
Description	Wavelet Transform is a superior approach to other time frequency analysis tools because its time scale width of the window can be stretched to match the original signal especially in image analysis.By using SOFM technique,we have made an attempt in employing lossy technique i.e., Vector Quantisation to encode the sub bands formed by the application of wavelet Transform.
