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.   THE STUDY ON THE GEOMETRIC SIMILARITY OF DEBRIS FLOW DEPOSITION 会议论文  OAI收割 5th DFHM, 意大利帕多瓦, 2011.6.14-6.17 作者:  Ou Guoqiang（欧国强）;  You Yong（游勇）;  Liu Jinfeng（柳金峰） 收藏  |  浏览/下载：9/0  |  提交时间：2013/01/07 geometric similarity  debris flow  deposition  laboratory experiments   Estimating leaf area index by inversion of reflectance model for semiarid natural grasslands 期刊论文  iSwitch采集 Science in china series d-earth sciences, 2009, 卷号: 52, 期号: 1, 页码: 66-84 作者:  Zhang Na;  Zhao YingShi 收藏  |  浏览/下载：28/0  |  提交时间：2019/05/10 Leaf area index  Plant crown shape  Geometrical similarity parameter  Reflectance model  Radiative transfer  Geometric optics  Inversion  Semiarid natural grassland   Geometric moment invariants 期刊论文  OAI收割 PATTERN RECOGNITION, 2008, 卷号: 41, 期号: 1, 页码: 240-249 作者:  Xu, Dong;  Li, Hua   |  收藏  |  浏览/下载：16/0  |  提交时间：2019/12/16 geometric primitive  moment invariant  similarity transformation  symbolic computation   The Role of Tillage in Soil Redistibution Within Terraced Fields on The Loess Plateau, China: An Investigation Using Cesiun-137 会议论文  OAI收割 Warsaw, 1993 作者:  Quine T.A.;  Walling D.E.;  Zhang X.   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/11/08 Building projects  Debris flows  Experimental conditions  Geometric similarity  Laboratory experiments  New constructions  Parabolic distribution  Plane configurations
