Fwivq

$ \bigcirc$Macro


Fwivq Reconstruct an image compressed by vector quantizing its wavelet transform




$ \bigcirc$Usage


Fwivq [-b1 BiFilt1] [-b2 BiFilt2] [-o OrthoFilt] [-e EdgeFilt] compressfile codebook


$ \bigcirc$Description


This macro reconstructs an image from the compressed file compressfile, which has been generated using the wavelet transform + vector quantization module fwvq (or the Fwvq macro). It is based on the fwivq module, but is simpler to use.

One only has to specify the prefix codebook of all codebook sets (see Fwvq and Fwlbg_adap macro documentations for further details on the codebook sets managment) and the input compressed file (typically a *.comp file generated with Fwvq macro).

If the input compressed file has the form *c.comp, then the reconstructed image is put in *r.rim.

All the options should be selected and tuned in exactly the same manner at the compression (Fwvq) and decompression (Fwivq) steps. Likewise, codebook should be the same at the compression (Fwvq) and decompression (Fwivq) steps. Then *r.rim should be identical to the image *q.rim obtained with Fwvq.
