Abstract

Fingerprint compression is a great problem. The purpose of this work is to identify a convenient scheme for fingerprint compression. Lossy and lossless techniques were considered. Regarding the lossy techniques, six lossy image compression techniques (Wavelet, Wavelet Packet, EZW, WSQ, JPEG, JPEG2000) were investigated. Comparison was performed using the Peak Signal-to-Noise Ratio (PSNR), the Signal to Noise Ratio (SNR) and the correlation coefficient. Three lossless compression techniques ( JPEG, JPEG2000 and JPEG-LS were also investigated to identify the highest average compression ratio.
