Compression of grey-scale fingerprint images

Abstract

Investigates a number of techniques developed for fingerprint identification. The test implementations include: ISO/CCITT JPEG developed cosine transform; local cosine transform; best basis-adaptive wavelet transform plus uniform quantisation; wavelet vector quantisation; and wavelet scaler quantisation. All of the above algorithms are viewed from a multifrequency or subband decomposition perspective. The results of ad hoc tests are summarised.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
