摘要

研究了一些用于指纹识别的技术。测试实现包括:ISO/CCITT JPEG开发余弦变换;局部余弦变换;最佳基自适应小波变换加均匀量化小波矢量量化;小波标量量化。以上所有算法都是从多频或子带分解的角度来看待的。总结了特别试验的结果

Compression of grey-scale fingerprint images

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.<>
