摘要/Abstract

摘要： 在手背静脉图像采集时由于手背旋转和平移等原因,会造成采集有效识别区域时出现偏差,给识别带来干扰,为实现快速定位有效识别区域,依据采集图像的特点,提出了一种基于最大内切圆的感兴趣区域提取算法。针对采集的手背静脉图像,计算最大内切圆心与质心,并利用内切圆心与质心计算手背的旋转角度,根据旋转角度矫正手背静脉图像位置,提取感兴趣识别区域。该算法基于手背轮廓,不受人为因素的干扰,可以消除平移和旋转的影响。实验结果表明该方法具有很好的鲁棒性。

Abstract: The rotation and translation of dorsal hand result in deviation, which brings interference during recognizing valid region when collecting dorsal hand vein image. In order to locate valid recognition area quickly, an extraction algorithm for region of interest based on maximum inscribed circle is proposed in view of the characteristics of the collected image. For the collected dorsal hand vein image, this algorithm calculates the center of the maximum inscribed circle and the center of mass, and the rotation angle of the dorsal hand is calculated. The position of the dorsal hand vein image is corrected and the recognition region of interest is extracted by the obtained rotation angle. The algorithm is based on the contour of the dorsal hand and is not affected by human factors. It can eliminate the influence of rotation and translation. Experimental results show that the proposed method has good robustness.

Key words: dorsal hand vein, region of interest, maximum inscribed circle, center of mass, rotation correction
