Image Compression



A collection of simple routines for image compression using different techniques.

图象压缩的不同方法

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.
