Interactive wavelet-based image compression with arbitrary region preservation
Armando Manduca · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1992
We have developed a software module which performs 2-D and 3-D image compression based on wavelet transforms. The compression is not lossless, but the software allows the user to interactively determine the degree of compression (by viewing the results) and to interactively define specific regions of the image -- of any size and shape -- that are to be preserved with full fidelity while the rest of the image is compressed (again, viewing the results). These capabilities may be of interest in applications such as teleradiology.
