fingerprint image enhancement的意思|示意

This paper just studied and discussed the fingerprint image enhancement.

本文所做的正是指纹图像增强方面的一些研究。

Periods and local direction of fingerprint image are the important structure characters. The two characters of structure are important in the fingerprint enhancement.

指纹图像的周期性和局部方向性是指纹图像的重要结构特征，充分利用这两个结构特征是提高指纹增强算法的重要方法。

The results prove that the effect of fingerprint image enhancement is obvious.

实验结果证明，指纹图象增强效果显著。

This paper introduces a fingerprint image enhancement algorithm based on fingerprint line orientation.

该文介绍了一种基于指纹线方向的指纹图像增强算法。

Enhancement and binarization algorithm are the emphases among them. According to fingerprint feature, orientation map is calculated, and image is denoised by orientation filters.

重点研究图像的预处理增强算法和二值化算法，根据指纹图像的方向性信息求出方向图，并利用方向滤波器对原图像进行滤波去噪。

To reduce the noise influence on fingerprint identification pretreatment, the process of fingerprint image is need, such as fingerprints image enhancement.

为减小噪声的影响，须在指纹识别预处理过程中对指纹进行优化，如进行指纹图像增强。
