This paper designs and realizes an image mosaic technique based on the information of edge. The technology is suitable for engineering application. First of all  two images of the adjoining frames are processed by convolution operation  get the edge images. And then we cut edge image into pieces and compute their spatial frequency. According to the value of the spatial frequency select reasonable registration model group. We compute correlation strength and the value of movement offset which are the model group and the current frame edge image. We can complete image mosaic by them. We use video sequence which of the resolution is 1024 * 768 do the experiment. The results show that the method has good effect and strong adaptability. Algorithm is high efficiency which running time is 24 ms. It is suitable for real-time processing requirements of the application. This method is an effective mosaic technique which is suitable for engineering application. 2012 IEEE.   景观生态学的核心:生态学系统的时空异质性 期刊论文  OAI收割 生态学杂志, 2000, 卷号: 1, 期号: 2, 页码: 42-49 邱扬; 张金屯; 郑凤英 收藏  |  浏览/下载：27/0  |  提交时间：2015/06/11 landscape ecology  spatial and temporal heterogeneity  spatial mosaic  flux in landscape  hierarchy and scale  human influence.
