摘要

针对集成电路封装行业，提出了一种亚像素精度的快速图像配准算法。该算法以点相关法为基础，主要从两个方面进行改进。一种是利用熵作为相关度量函数，另一种是提出两两交换算法来获取预定义的点集。它还包括样条插值模型，确保算法具有亚像素精度。仿真结果验证了该算法的有效性。

A point correlation based subpixel image registration algorithm

This paper presents a fast image registration algorithm with sub-pixel accuracy for IC package industry. The algorithm is based on point correlation method and improved mainly in two aspects. One is using entropy as correlation measure function and the other is proposing pair-wise exchange algorithm to obtain the pre-defined set of points. It also includes spline interpolation model that ensures the algorithm with sub-pixel accuracy. Simulation results confirm the validity of the presented algorithm.
