本文提出了一种新的手指生物识别方法。首先捕获红外手指图像,然后使用改进的高斯高通滤波器通过二值化、局部二值模式(LBP)和局部导数模式(LDP)方法进行特征提取。红外手指图像包括手指静脉和手指几何形状的多模态特征。改进的高斯高通滤波器是完全卷积的,而不是用不同的方法提取每个特征。因此,提取的手指图像二值模式包含了静脉和手指几何的多模态特征。实验结果表明,该方法的误差率为0.13%。
In this paper, we propose a new finger biometric method. Infrared finger images are first captured, and then feature extraction is performed using a modified Gaussian high-pass filter through binarization, local binary pattern (LBP), and local derivative pattern (LDP) methods. Infrared finger images include the multimodal features of finger veins and finger geometries. Instead of extracting each feature using different methods, the modified Gaussian high-pass filter is fully convolved. Therefore, the extracted binary patterns of finger images include the multimodal features of veins and finger geometries. Experimental results show that the proposed method has an error rate of 0.13%.
