摘　　要：本文以静脉特征识别为目标,提出了一种基于优化区域OTSU的静脉图像分割算法。该算法首先优化OTSU计算流程,减少求解OTSU阈值的计算量;然后优化OTSU阈值求解结构,降低OTSU阈值求解次数。实验结果表明,该算法分割效果好、耗时少,能够满足实际应用要求。This paper presents an algorithm for vein image segmentation based on optimal regional OTSU for use of vein recognition. Firstly, optimize the computation flow for decreasing the computation time to determine thresholds. Secondly, optimize the structure for reducing the computation times to use OTSU. The experiments show that this algorithm gets good results for image segmentation and costs little time. It can satisfy the need of application.
