波形匹配算法，为了获得完整的指纹图像，提出一种基于波形匹配的指纹图像帧序列拼接算法．该算法从每个图像帧的参考区域提取波形信息，通过计算波形相似度并引入逐步求精的拼接策略，分3个阶段获得拼接参数，确定图像帧之间的重叠和水平移位．实验结果表明，文中算法运算量小、运算速度快、占用系统资源少，特别适用于资源有限环境中的自动指纹识别系统．-Waveform matching algorithm, in order to obtain a complete image of the fingerprint, the fingerprint image frame sequence assembly algorithm based on waveform matching. The algorithm waveform information extracted from the reference area for each image frame, and the introduction of the the splice strategy of stepwise refinement by calculation of the waveform similarity, divided into three stages to get the stitching parameters, to determine the overlap between the image frame and horizontal shift. The experimental results show that the arithmetic operations is a small amount of computing speed, occupying less system resources, particularly in resource-limited settings in the Automated Fingerprint Identification System.
