Cfwivq

$ \bigcirc$Macro


Cfwivq Reconstruct a color image compressed by vector quantizing its wavelet transform




$ \bigcirc$Usage


Cfwivq [-c] [-b1 BiFilt1] [-b2 BiFilt2] [-o OrthoFilt] [-e EdgeFilt] compressfile codebook_red [codebook_green codebook_blue]


$ \bigcirc$Description


This macro reconstructs a color image from the compressed files with prefix compressfile, which have been generated using the wavelet transform + vector quantization macro Cfwvq. It is based on the fwivq module (applied to each channel separately), and is simpler to use.

It works exactly in the same way that the Fwivq macro for graylevel images, except that there is a possibility to use different codebooks for the red, green and blue channels. The codebook arguments should be tuned in the same way as during the compression step (Cfwvq).

The macro looks for the input compressed files compressfiler.comp, compressfileg.comp and compressfileb.comp. The reconstructed image is put in compressfiler.rim.

All the options should be selected and tuned in exactly the same manner at the compression (Cfwvq) and decompression (Cfwivq) steps.
