To reduce the omission of bridges by searching the edge  we extract the river regions which the bridges are included in. Firstly  we segment the optical image to get the coarse water bodies using iterative threshold  eliminate the noise regions and add the missing regions based on k-means clustering with texture information and spatial coherence. Then  the blanks are connected based on shape features and candidate bridge regions are segmented from river regions. Finally  the bridges are verified by geometric information and the ubiety between bridges and river. The results show that this approach is efficient and effective for extracting bridges in satellite image from Google Earth and in aerial optical images acquired by unmanned aerial vehicle. 2011 IEEE.   视觉监控中的目标跟踪研究 学位论文  OAI收割 工学博士, 中国科学院自动化研究所: 中国科学院研究生院, 2010 作者:  李敏 收藏  |  浏览/下载：87/0  |  提交时间：2015/09/02 Omega形状  方向滤波的金字塔统计量  简化的生物启发特征  姿态估计器  增量自调节粒子滤波  底层启示模型  MCMC粒子滤波  Omega-shape  Pyramidal Statistics of Oriented Filtering  Simplified Biologically Inspired Features  Pose Estimator  Incremental Self-tuning Particle Filtering  low-level cues  MCMC-particle filtering   Computer simulation research on cognitive mechanism of human vision (EI CONFERENCE) 会议论文  OAI收割 International Conference on Measuring Technology and Mechatronics Automation, ICMTMA 2010, March 13, 2010 - March 14, 2010, Changsha, China Ke H.; You W. 收藏  |  浏览/下载：37/0  |  提交时间：2013/03/25 The development of intelligent system which accorded with human cognitive mechanism will exert a profound influence on national defense  economy  education  culture and etc. A computer simulation method according with cognitive mechanism of human vision was proposed on the basis of Structural Decomposition Theory. Many basic shape feature information tables of similar object from different side can determine a kind of object uniquely. System weighted basic shape features in two different information tables by membership degree and then calculated similarity. The identifying object which had the maximum similarity with it in system was what we needed. The system used 83 pictures of 6 kinds of objects with different side for training and testing. The experiment results demonstrated  task of basic shape extraction  object recognition and others can be completed effectively with the method in paper. The method in paper can be a new attempt on computer simulation method according with cognitive mechanism of human vision from cognitive field. 2010 Crown Copyright.   SAR AND OPTICAL IMAGES REGISTRATION USING SHAPE CONTEXT 会议论文  OAI收割 2010 Ieee International Geoscience and Remote Sensing Symposium, New York Huang, Lei; Li, Zhen; Zhang, Rui 收藏  |  浏览/下载：20/0  |  提交时间：2014/12/07 Image registration  edge features  feature dilation  shape context  airborne
