Description: This paper describes the evolution of new wavelet and scaling numbers for optimized transforms that consistently outperform the 9/7 discrete wavelet transform (DWT) for fingerprint compression and reconstruction. The FBI fingerprint compression standard [2] is based upon the biorthogonal 9/7 wavelet filter pair developed in 1992 by Cohen, Daubechies, and Feauveau [3]. Platform: |

Description: A new fingerprint compression algorithm based on
sparse representation is introduced. Obtaining an overcomplete
dictionary from a set of fingerprint patches allows us to represent
them as a sparse linear combination of dictionary atoms.
In the algorithm, we first construct a dictionary for predefined
fingerprint image patches. For a new given fingerprint images,
represent its patches according to the dictionary by computing
l0-minimization and then quantize and encode the representation.
In this paper, we consider the effect of various factors on compression
results. Three groups of fingerprint images are tested.
The experiments demonstrate that our algorithm is efficient
compared with several competing compression techniques (JPEG,
JPEG 2000, andWSQ), especially at high compression ratios. The
experiments also illustrate that the proposed algorithm is robust
to extract minutiae. Platform: |
