摘要
指纹图像分割是指纹自动识别的重要组成部分。本文是把直方图技术和高斯统计分布函数有效地结合起来,作为求取指纹图像二值化阈值的理论基础,在此基础上提出一种称之为“黄金分割算法”的最优化阈值法,计算机仿真结果表明利用该算法图像分割结果比较理想。
Image segment is the important technique in fingerprint image processing and recognition. Histogram technique is an important technique of image segment. The distribution of a gray-level image is often similar to that of Gaussian distribution. So the combines the histogram technique with Gaussian distribution function, achieving a theory basis of image segments. From the analysis of the theoretical expression of this theory, the article puts forward a new threshold method--Golden section method, gets the iterative formulas and steps on how to work out the threshold in image segment . At last, the article uses two examples to prove this method.
