We have very good results in lossless compression of fingerprints, EEG, ECG, texts, and other similar kind of visual information. We developed methods and algorithms of our own and this permits successfully to adapt our approach depending on the application in order to get even higher efficiency. Some of our results are given in corresponding publications, (accessible).
Dear Roumiana Kountcheva for a long time WSQ and JPEG 2000 have been the compression standard for fingerprint images. Although both are lossy compression methods they achieve great results on ensuring the efficacy of an Automatic Fingerprint Identification System. You said that in the past you have obtained great results in lossless compression of fingerprints. I have great interest in seeing how the compression ratio of your algorithms compare with those of WSQ and JPEG 2000. I would appreciate if you can suggest me some of your papers if in the past you have conducted similar comparisons. I will also be very happy to collaborate on this topic or a similar one in a future with you. Best regards
I know all this.
Most papers are accessible and there are comparison results..
