摘　　要：针对CCD光学指纹取象设备普遍遇到的纹线断裂情况,提出了用广义Hough变换使纹线复原的原理和方法,论文详细描述了Hough变换和广义Hough变换的指纹图像边缘提取算法,结合DSP6000测试板进行了实验研究,对自动指纹识别技术的研究具有一定的实际意义。A method was brought forward to recover the lines of the fingerprint image with generalized HOUGH transform, and the arithmetics of picking up lines form fingerprint image with HOUGH transform and generalized HOUGH transform was described. Many experiments were done on DSP6000 testing board. It has practical significance for the research of automated fingerprint i- dentification system.
