I wish to compare a single image lossless image compression scheme of mine with benchmark compression schemes. My criteria for compression are speed, CR and robustness. Robustness is defined here as the ability of the compression scheme to depict good CRs over a large range of image data of various types (such as CFA, Raster etc)
Sir, I hope you referred this webpage (http://imagecompression.info/lossless/). I am not sure but may be useful for you.
Hello,
just interested I tried 7-Zip on one of the file sets (8 bit) on imagecompression.info
This may be considered unconventional, but a compression rate of 58 % overall for a "general purpose lossless compressor" is quite impressive. (Algorithm: LZMA)
Just for reference you may try out the other algorithms 7-Zip is offering - or try algorithms dealing with line-difference pre-processing.
Regards
Most of wavelet based image coding algo are lossless as well as lossy. Refer JPEG2000,
SPIHT, SPECK and listless version BCWT, WBTC
May be useful for you to add in comparision

Regarding the 'vanishing' of the 1st link: seems Matsuda left the Institution and his personal webspace was deleted in this context.
I could find some contribution by Ichiro Matsuda:

But it's up to you to judge whether this is the text you wanted to provide.
