一方面磁性聚合物微球可通过共价键来结合酶、细胞和抗体等生物活性物质；另一方面因其具有"在外界磁场存在下能定向运动"这一特殊性能，可对外加磁场表现出强烈的磁响应性，因此它被用作酶、细胞、药物等的载体，广泛地应用到生物医学、细胞学和生物工程等领域。

Then, the minutiae sets are aligned globally through coordinate transform, and the alignment parameters are optimized by using affine transform and least square method. Finally, minutiae matching and directional field matching are respectively achieved based on the minutiae alignment, and the two matching scores are fused into a single to obtain a more reasonable result. Experimental results show that this method contributes to ensure the accuracy of fingerprint identification as well as possesses the real-time performance.

该算法首先利用脊线信息快速确定满足局部匹配要求的细节点对，在此基础上进一步通过全局坐标变换完成细节点的全局配准，并采用仿射变换模型通过最小二乘估计对配准参数进行优化，然后在配准的基础上分别进行细节点匹配和方向场匹配，最后对两种匹配分值进行融合，以取得较合理的匹配结果。
