wavelet WAVELET SOFTWARE FOR GENERAL APPLICATIONS AND IMAGE COMPRESSION ============================================ NOTE: The wavelet product has some public, readable files; but the main sources are encrypted with a Decryption Key that must be purchased from PSI. DECRYPTION INSTRUCTIONS: After purchasing the Decryption Key, you compile and run the decryptor like so (for many Unix systems): % cc -O psidec.c -o psidec On the Win32 platforms, Microsoft compiler, you need to add a certain compiler option to be able to use wildcard '*': % cl -W4 psidec.c -link setargv.obj The executable "psidec" can now be used on a PSI-encrypted file "file.pse:" % psidec file.pse or, to conveniently decrypt everything, say, in the current directory, you can go: % psidec *.pse The useable product obtained via successful decryption will have its filename automatically assigned consistent with the PSI documentation. ============================================ Updates: 6 Jul *** JF (Image compression added) 11 Oct 97 RW 9 Sep 97 JF (creation) c. 1997-2001 Perfectly Scientific, Inc. All Rights Reserved. ____________________________________________ OVERVIEW This software package, wavelet, contains a library of functions for performing fast wavelet transforms (FWVTs) and a lossy wavelet image compressor. The wavelets of choice are the celebrated Daubechies wavelets. However, the basic algorithm structures easily extend to other wavelet classes. ____________________________________________ CONTENTS: images: Folder containing a collection of test images for use with the image compression programs. main: primary folder for running the wavelet compression programs psiwc and psiwd. sources: Contains all of the functions pertaining to the wavelet and laplacian transforms, as well as psiwc.c and psiwd.c which are implementations of wavelet compression. transfor: Folder containing a collection of programs that utilize the fast wavelet algorithm. ____________________________________________ END
