Hi, wavelet transformation can be effectively used for lossy compression of measurement/process data. This gets more and more important because of modern quality management systems. Data compression is usually very complicated. While I was working on the denoising of EDX-scans with wavelet transformation, I found it possible to do lossy data compression very easily by putting wavelet transformation followed by quantization to small integers in front of loss-less compression with gzip.
I am intending to make a program wzip to do this preprocessing, leaving the difficult task to gzip. The program will use the Haar-wavelet transformation. Any suggestions are welcome.
