image Compression
A collection of simple routines for image compression using different techniques.
圖象壓縮的不同方法
BTCODE:
image compression Using Block Truncation Coding.
PYRAMID:
image compression based on Gaussian Pyramids.
DCTCOMPR:
image compression based on Discrete Cosine Transform.
IMCOMPR:
image compression based on Singular Value Decomposition.
The given codes can be also used in 2D noise suppression.
Notes:
The function "conv2fft" performs a 2D FFT-based convolution.
Type "help conv2fft" on Matlab command window for more informations.
These MATLAB functions were created for the book Digital image
Processing Using MATLAB (DIPUM), by R.C. Gonzalez, R.E. Woods, and
S.L. Eddins, Prentice Hall, 2004, ISBN 0130085197. The functions
supplement and extend the image processing functionality of MATLAB
and the image Processing Toolbox, both offered by The MathWorks.
