摘要 图像细化是指纹预处理技术中的一个重要环节,大多数指纹识别算法都是在细化图像上实现特征点的检测。因此,研究图像细化对提高指纹识别系统的性能具有重要意义。对OPTA算法进行了改进,将其应用在指纹图像细化中,并对其局限性进行了分析。实验结果表明,使用改进的OPTA算法,指纹图像细化效果有明显的提高。 Image thinning is one ofimportant preprocessing procedures for fingerprint images. Most offingerprint recognition algorithm ehecks the special points by image thinning. Therefore, researchofimagethinningisimportanttoimprovetheperformaneeoffingerprint recognition system. The OPTA thinning algorithm is improved and applied to image thinning, at the same time, its limitation is analyzed. Experimental results indicate that the improved OPTA thinning algorithm is better in fingerprint image thinning.
