WPCCOMPRESS --- COMPRESS a 2D section using Wavelet Packets wpccompress < stdin n1= n2= [optional parameters ] > stdout Required Parameters: n1= number of samples in the 1st dimension n2= number of samples in the 2nd dimenstion Optional Parameters: error=0.01 relative RMS allowed in compress ", Notes: This program is used to compress a 2D section. It compresses in both directions, vertically and horizontally. The parameter error is used control the allowable compression error, and thus the compression ratio. The larger the error, the more the more compression you can get. The amount of error depends on the type of data and the application of the compression. From my experience, error=0.01 is a safe choice even when the compressed data are used for further processing. For some other applications, it may be set higher to achieve larger compression. Caveats: For the current implementation, the compressed data themselves are NOT portable, i.e., the data compressed on one platform might not be recognizable on another.
