基于SLER检测的红外与可见光图像自动配准

针对可见光图像和红外图像配准问题，提出了一种新的自动配准方法.该算法通过同级极值区域检测子在灰度梯度图像上提取仿射协变区域.然后利用超图匹配算法确定匹配点对实现图像配准.该方法尤其适合于红外图像的质量或者边缘比对应的可见图像质量或边缘差情况下的异模配准.对一些具有挑战性的图像对进行试验，实验结果表明我们提出的方法比其他方法获得了更好的性能.

Abstract

A novel approach to the problem of visible and infrared automatic image registration was proposed. The registration is performed by extracting affine covariant regions through same level extremal region (SLER) detector on a gray gradient image. Then, hypergraph matching algorithm was employed to obtain identical key points. The approach is especially suitable for registering multi-sensor infrared images where the quality of images or the corresponding edge maps are worse than the counterparts on a common optical image. Experiments performed on several challenging real image pair show that our proposed method achieves better performance than other approaches.
