Presents two preprocessing methods for finger-print image. The first method adopts dynamic threshold to detect the threads of finger-print, and gives the bilevel image directly. The second method consits of three pro cedures: first eliminates low frequeucy grey level disturbance by use of local statistics, then enhances the threads of finger-print and attenuates high frequency noise by matching masks, finally transforms the image into bilevel version. The fast algorithm of the second method is also discussed.

提出两种指纹图象的预处理方法。第一种方法采用动态门限检测指纹的隆线,直接给出二值化象图。第二种方法包括三个步骤:首先利用图象的局部统计特性消除低频灰度干扰;然后通过匹配模板增强指纹隆线,抵制高频噪声;最后进行二值化。还讨论了第二种方法的快速算法。

Two preprocessing methods for finger-print images are presented in this paper. In the first method, a dynamic threshold is used to detect the finger-print lines and get a bilevel image directly. There are three steps in the second method. The low frequency grey level disturbance is eliminated by use of local statistics. Then the finger-print lines are enhanced and the high frequency noise is attenuated by matching masks. Finally, the image is transformed into a bilevel version.

本文从理论上给出了树分类器的数学定义,探讨了分类树的优化和性能评价函数这两个关键问题。从而提出了在卫星多光谱数据分类中切实可行的优化树分类器设计方法,包括合理的性能评价函数、新型的分类树数据结构和搜索的优化算法。最后给出了应用于森林分类的实验结果。

To meet the special demands for finger print image compression of automatic finger print identification system, this paper has proposed a new evaluation criterion for finger print image compression and a new finger print image compression algorithm based on wavelet transformation and minutia region protection.

指纹自动识别系统因其本身的特殊性对指纹图像压缩提出了特殊的要求,为满足这些要求,我们提出了面向指纹自动识别的指纹图像压缩的评价标准和基于小波变换的考虑特征点区域的指纹图像压缩算法。
