Abstract

NIST provided in a special publication guidance for the compression of 1000 ppi fingerprint images using Part I of the JPEG 2000 standard. The present document extends the Guidance to the compression of 1000 ppi palm and whole-hand images. The NIST Spectral Image Validation Verification (SIVV) metric was used to determine JPEG 2000 compression ratios at which palm and hand images exhibit spectral fidelity to non-compressed source images comparable to that of fingerprint images compressed at 10:1. The investigators discuss the effect of untextured regions in enabling compression ratios as high as 12:1 for palms and 22:1 for whole hand images as indicated by the spectral analysis. However, they note several factors contraindicating deviation of compression ratio from that recommended in the Guidance. Hence, NIST recommends that a single compression ratio, 10:1, be applied to all friction ridge impression types to ensure interoperability, in general, and support of latent matching, in particular.
