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.   Holomorphic two-spheres in complex grassmann manifold g(2,4) 期刊论文  iSwitch采集 Proceedings of the indian academy of sciences-mathematical sciences, 2008, 卷号: 118, 期号: 3, 页码: 381-388 作者:   收藏  |  浏览/下载：30/0  |  提交时间：2019/05/10 Gaussian curvature  Holomorphic map  Totally geodesic   A method for condition monitoring and fault diagnosis in electromechanical system 期刊论文  OAI收割 Neural Computing & Applications, 2008, 卷号: 17, 期号: 4, 页码: 373-384 作者:  Guo QJ(郭前进);  Yu HB(于海斌);  Hu JT(胡静涛);  Xu AD(徐皑冬) 收藏  |  浏览/下载：40/0  |  提交时间：2012/05/29 Fault diagnosis  Electrical machines  Kernel independent component analysis  Kernel trick  Gaussian chirplet distributions  Self-organizing map
