The difficulty of infrared and visible image registration is to find a reasonable similarity definition. In this paper, we develop a novel image similarity called implicit linesegment similarity(ILS) and a registration algorithm of infrared and visible images based on ILS. Essentially, the algorithm achieves image registration by aligning the corresponding line segment features in two images. First, we extract line segment features and record their coordinate positions in one of the images, and map these line segments into the second image based on the geometric transformation model. Then we iteratively maximize the degree of similarity between the line segment features and correspondence regions in the second image to obtain the model parameters. The advantage of doing this is no need directly measuring the gray similarity between the two images. We adopt a multi-resolution analysis method to calculate the model parameters from coarse to fine on Gaussian scale space. The geometric transformation parameters are finally obtained by the improved Powell algorithm. Comparative experiments demonstrate that the proposed algorithm can effectively achieve the automatic registration for infrared and visible images, and under considerable accuracy it makes a more significant improvement on computational efficiency and anti-noise ability than previously proposed algorithms.   基于人眼视觉特性的图像结构差异性杂波度量 会议论文 第十届全国光电技术学术交流会, 北京, 2012年6月12日至17日 作者:  罗海波;  徐德江;  史泽林 收藏  |  浏览/下载：11/0  |  提交时间：2012/12/28 图像杂波  度量  结构差异性  颜色显著性  方向对比度显著性  目标获取性能  视觉显著性   A field transition particle filter tracking algorithm 会议论文 International Symposium on Photoelectronic Detection and Imaging 2011: Advances in Infrared Imaging and Applications, Beijing, China, May 24-26, 2011 作者:  Xu DJ(徐德江);  Shi ZL(史泽林);  Yu XR(于新荣);  Ding QH(丁庆海);  Luo HB(罗海波) 收藏  |  浏览/下载：13/0  |  提交时间：2012/06/06
