摘要
指纹图像质量的好坏对自动指纹识别系统的性能有着重要的影响,如何有效地评测指纹图像的质量和排除低质量的指纹图像是一个比较难的问题。从宏观和微观两方面出发,通过多个关键的评测指标来判断所采集的指纹图像是否符合一定的质量标准,对不符合质量标准的指纹图像要求重新采集,最后对指纹图像质量提出了更完整的评价体系。该评测方法是在充分考虑了指纹识别系统的特点之后提出,因此能很好地评测指纹图像的质量,从而提高系统的准确性和可靠性。
The fingerprint image quality evaluation is crucial in eliminating poor fingerprint image. This will heavily affect the performance of fingerprint identification system. The question is how to evaluate the quality of the fingerprint image effectively and how to obviate the low quality of the fingerprint image. Discuss several important macroscopical evaluation parameters and microcosmic evaluation parameters, and then apply them to estimate the fingerprint image quality. At last,put forward the more complete evaluation system for the captured fingerprint image qualities. Based on the analysis and study of grey image, this method is put forward, so the reliability and veracity of fingerprint recognition system is improved.
