waveppm(1)

NAME

waveppm - perform Wavelet transforms on a color image

SYNOPSIS

waveppm [-s] <infile> <transformed> [stages [filter [<reconstructed> [<beautified>]]]]

DESCRIPTION

waveppm opens infile, performs a Wavelet transform on it writing the result to transformed. Normally, a Pyramid decomposition will be used, only if -s is given, a Standard decomposition will be used instead. If specified, the Wavelet transform will be performed over stages stages instead of the default number 1. Also a different filter than Daub4 can be chosen. If a reconstructed image name is given, the inverse transform will be performed and the result written to that file. Finally, if a beautified image name is given, the transformed image will be beautified according to the number of transform stages, so that it looks better in presentations (the ratio between LL and other parts will be changed, so that the image is not really an exact representation of the transform anymore).

NOTES

The waveppm utility is part of the Wavelet class library package. The version number refers to the whole package rather than to the utility.

Apart from PPM, waveppm also accepts JPEG and may, if enabled, be able to read PFI files.
