Attenuation of half-tone background detail from fingermark images using digital image processing techniques
Frequency domain processing of fingermark images is valuable for reducing interfering periodic backgrounds. The success of the processing and the quality of the results depend upon a number of factors including structure and chosen processing method. This paper shows that in some circumstances it is possible to determine the most appropriate frequency domain filter for attenuation of interfering backgrounds using automatic computer based generation of frequency domain filters. Success has been achieved with half-tone printed backgrounds.
