The Wavelet Scalar Quantization Compression Standard for Digital Fingerprint Images
نویسندگان
چکیده
A new digital image compression standard has been adopted by the US Federal Bureau of Investigation for use on digitized gray-scale fingerprint images. The algorithm is based on adaptive uniform scalar quantization of a discrete wavelet transform image decomposition and is referred t o as the wavelet/scalar quantization standard. The standard produces archival quality images at compression ratios of around 20:l and will allow the FBI t o replace their current database of paper fingerprint cards with digital imagery.

The Fbi Compression Standard for Digitized Fingerprint Images
The FBI has formulated national standards for digitization and compression of gray-scale fingerprint images. The compression algorithm for the digitized images is based on adaptive uniform scalar quantization of a discrete wavelet transform subband decomposition, a technique referred to as the wavelet/scalar quantization method. The algorithm produces archival-quality images at compression rati...
متن کاملWavelet Scalar Quantization
Fingerprints are today the most widely used biometric features for personal identification. With the increasing usage of biometric systems the question arises naturally how to store and handle the acquired sensor data. Our algorithm for the digitized images is based on adaptive uniform scalar quantization of discrete wavelet transform sub band decomposition. This technique referred to as the wa...

1278 NOTICES OF THE AMS VOLUME 42, NUMBER 11 T he new mathematical field of wavelet transforms has achieved a major success, specifically, the Federal Bureau of Investigation’s decision to adopt a wavelet-based image coding algorithm as the national standard for digitized fingerprint records [11, 4, 3]. The FBI standard, which uses an approach known as wavelet transform/scalar quantization (WSQ...
متن کاملA novel efficient image compression system based on independent component analysis
Next generation image compression system should be optimized the way human vision system (HVS) works. HVS has been evolved over millions of years for the images which exist in our environment. This idea is reinforced by the fact that sparse codes extracted from natural images resemble the primary visual cortex of HVS. We have introduced a novel technique in which basis functions trained by Inde...
متن کاملA New Wavelet Domain Feature for Fingerprint Recognition
A new fingerprint recognition approach based on features extracted from the wavelet domain is presented. The 64-subband structure proposed by the FBI WSQ standard is used to decompose the frequency of the image. The efficiency of the method is achieved by using the k-nearest neighbor (k-NN) classifier. The result is compared with other image-based methods. For compressed fingerprint images, thi...
