Abstract
The aim of this paper is to discuss the important features of wavelet transform and other existing methods in compression of fingerprints. Image quality is measured objectively using peak signal-to-noise ratio (PSNR). A comparative study among discrete cosine transform based joint photographic experts group (JPEG) standard, embedded zerotree wavelet (EZW) scheme and JPEG2000 is done. The study shows that EZW and JPEG2000 results in compression ratio 40:1 which is much higher than the existing FBI wavelet/scalar quantization (WSQ) standard that offers best compression at 26:1. Our results helps application developers to choose a good wavelet compression system for their applications.
