The files in this directory are data for some of the plots and demonstrations in the textbook. The files come in three categories: I) Wavelet and scaling function files II) Blind source separation demonstration files III) Test image for emission tomography example ------------------------------------------------------------------ I) Wavelet and scaling function files The ascii files d41 d42 d61 d62 d81 d82 d101 d102 d121 d122 contain scaling functions (file names ending in 1) and wavelet functions (file names ending in 2). The time parameter and the function value are represented in these two-column files. ------------------------------------------------------------------ II) Blind source separation demonstration files They files to demonstrate blind source separation were recorded using the xwave tool (v.0.6) on a linux workstation at 8000 samples/second, 8 bits/sample, using a low-quality (office-style) microphone. tkm.wav is the voice of Todd Moon, reading about blind source separation. ag.wav is the voice of Amy Griffin, reading some nameless memo. vm.wav is from the track "Voice Male," of the all-vocal group, Voice Male, off their album "up, up and away," copyright 1997 Voice Male. Used by permission. Recording of the first two sources was accomplished by speaking directly into the microphone. Recording of the third source was accomplished by playing the CD into the microphone. In all cases, the artifacts due to the recording process (hiss, pop, and quantization noise) can be heard by playing the original unmixed files. (You should really here Voice Male off the original CD to appreciate it!) It may be observed thus that the artifacts heard in the final separated output files are due mostly to recording artifacts, and not the separation process. .wav files: Original (unmixed) files: vm.wav ag.wav tkm.wav Mixed files (input data): bssin1.wav bssin2.wav bssin3.wav Separated (output) files: bssout1.wav bssout2.wav bssout3.wav ------------------------------------------------------------------ III) Test image for emission tomography example im1.mat is a simple test image used for the emission tomography example.
