At the first  we get the weight image from the target candidate region. Then  we analyze the differences between the object and background. According to that  the area estimation of the target can be converted into the image segmentation task. To realize the adaptive segmentation and estimation  we define the threshold as the maximum variance between object and background. Combining the estimated area and covariance matrix  we can estimate the width  height and orientation of the object. The experimental results on three representative video sequences validate its robustness to the deformable estimation of the targets. 2010 IEEE.   Extracting sea-sky-line based on improved local complexity (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China 作者:  Zhang Y.-F. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 Sea-sky-line extraction under complicated sea-sky background is an important aspect of long-range target tracking research. An algorithm based on improved local complexity is proposed according to the feature that the sky and the sea usually show up at different gray levels in sea-sky background images. Median filter is applied first to remove peak noise  and then the point set of sea-sky-line region which has the greatest change in image is obtained by calculating the local complexity of image and selecting a segmentation threshold. Finally  Hough transform is used to extract the sea-sky-line. The experiment results indicate that this method can extract sea-sky-line under simple and complicated sea-sky backgrounds  which is robust and can improve noise immunity of the algorithm. 2010 IEEE.   Adaptive resolution storage system based on LOG-POLAR transform for multi-target trackers (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer Application and System Modeling, ICCASM 2010, October 22, 2010 - October 24, 2010, Shanxi, Taiyuan, China 作者:  Zhang Y. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 The main constrained problem of the video monitoring and storage system is the contradiction between large field of view and storage space limitations. Not all of the video information introduced by the image sensors need to be recorded especially for some tracking system which has appointed functions to track specifically kinds of targets. For instance  the system not only works for single target  if the monitor is appointed for human face tracking  but also can work for multi-targets. High reconstruction resolution in the fovea region enables the successive application of recognition modules without sacrificing their performance  the best system appears to be concentrating on human face only and all the others considered being background  the low reconstruction resolution in the periphery helps to reduce the video data. 2010 IEEE.  the background regions needn't to be recorded in detail. For this purpose  this letter presents a real-time foveate storage system  which efficiently represents the video image in log-polar coordinates  with the foveate point centered on the target   Petrogenesis of the lianyunshan granites in northeastern hunan province, south china, and its geodynamic implications. 期刊论文  iSwitch采集 Acta petrologica sinica, 2009, 卷号: 25, 期号: 5, 页码: 1056-1078 作者:  Xu DeRu;  Wang Li;  Li PengChun;  Chen GuangHao;  He ZhuanLi 收藏  |  浏览/下载：40/0  |  提交时间：2019/05/10 Strongly peraluminous granite  Afc processes  Geodynamic background  Lianyunshan region in northeastern hunan province  Jiangnan oldland   Detecting of multi-target in sea or sky background based on wavelet energy (EI CONFERENCE) 会议论文  OAI收割 Advanced Sensor Systems and Applications II, November 8, 2004 - November 12, 2004, Beijing, China 作者:  Liu G. 收藏  |  浏览/下载：19/0  |  提交时间：2013/03/25 The technology of multi-target tracking is always detecting small targets in complex background. According to the frequency characteristic of nature background and small target  a method of detecting targets based on wavelet energy is suggested. The energy of targets in horizontal and vertical direction outclass that of background  or we can say  the gray degree of targets outclass that of background. Then through selecting adaptive region-value  targets and background can be divided. By the method of classifying  the figure centers of every target can be calculated. According to the figure centers of every target in several neighboring frames  the position and velocity of every target in next frame can be estimated by Kalman filter. Experiment results have shown that small targets in sea or sky nature background can be detected by this method  and they can be tracking.
