摘要
针对现有匹配算法存在的问题,本文提出了基于特征三角形的指纹匹配方法,并就三角形的构成进行了详细的介绍。实验表明,该方法具有旋转平移不变性和良好的抗噪能力,能有效地提高系统的识别性能。
To the problems that have been for long about matching methods, this paper presents a new one based on congruent triangle and makes a detailed presentation about the composing of congruent triangle. Experiment results demonstrate that the method is invariant to rotation and with amount of position changes and well performance of resisting noise. This method leads to improvement in system identification performance.
