YAWICA 0.01

YAWICA stands for Yet Another Wavelet based Image Compression Algorithm, it is the result of my diploma thesis. This source code is for educational purposes only and not for any commercial application. So it is neither optimized for speed nor does it accept other image material than PGM images with 256 grey levels. It is intended for photo realistic images and will give a poor performance on bilevel ones. Here some PSNR-values in dB for different images transformed with the 9/7-wavelet with 0.5 bpp in comparsion to SPIHT and EBCOT. picture resolution SPIHT EBCOT YAWICA lena.pgm 512x512 37.25 dB 37.32 dB 37.68 dB barbara.pgm 512x512 31.40 dB 32.31 dB 32.25 dB goldhill.pgm 512x512 33.13 dB 33.24 dB 33.49 dB mandrill.pgm 512x512 25.65 dB 25.58 dB 25.82 dB bike.pgm 2048x2560 33.01 dB 33.55 dB 33.66 dB cafe.pgm 2048x2560 26.49 dB 26.84 dB 27.24 dB woman.pgm 2048x2560 33.59 dB 33.65 dB 33.95 dB.
