Corona can be detected and imaged by using solar blind ultraviolet intensifier charge coupled device (SBUVICCD) without complex background to be processed. In this paper how to use ICCD to detect corona was analyzed. Imaging process of Gen II SBUVICCD was introduced and what will be noted during design instruments based on SBUVICCD to detect corona was also discussed. Some methods for deciding corona discharge level by using images from SBUVICCD were discussed sequentially. Finally  some corona pictures taken by using SBUVICCD were shown and expressed to support the items mentioned above. The result shows that SBUVICCD is suitable for corona detection in site.   Data mining-based engineering project grading technique 会议论文 7th World Congress on Intelligent Control and Automation, Chongqing, China, June 25-27, 2008 作者:  Chang CG(常春光);  Song XY(宋晓宇);  Gao B(高波);  Kong, Fanwen 收藏  |  浏览/下载：11/0  |  提交时间：2017/03/13 Data mining  Engineering project  Grading  Decision tree  C4.5 algorithm   Research of Face Detection System Applied for Detecting Faces with Complex Background and Illumination 会议论文 5th international conference on fuzzy systems and knowledge discovery, jinan, peoples r china, oct 18-20, 2008 Dai L; Li WJ; Chen X; Jin XX; Qu YF 收藏  |  浏览/下载：49/0  |  提交时间：2010/03/09 image preprocessing   Vision Based Target Tracking Algorithm in Natural Complex Scene 会议论文 4th International Conference on Natural Computation (ICNC 2008), OCT 18-20, 2008 作者:  Chang, Faliang;  Wang, Xiaolin;  Han, Jie;  Liu, Xue 收藏  |  浏览/下载：2/0  |  提交时间：2019/12/31 Target tracking  Mean-shift  Occlusion  Color feature  Background-weighted histogram   Hand gesture detection and segmentation based on difference background image with complex background 会议论文 Chengdu, Sichuan, China, July 29, 2008 - July 31, 2008 作者:  Zhang, Qiuyu;  Chen, Fan;  Liu, Xinwen 收藏  |  浏览/下载：11/0  |  提交时间：2020/11/15 Embedded software  Embedded systems  Image segmentation  Normal distribution  Palmprint recognition  Adaptive methods  Automatic threshold selection  Background image  Between-class variances  Complex background  Illumination changes  Optimal threshold  Segmented images   A method of hand gesture segmentation and tracking with appearance based on probability model 会议论文 Shanghai, China, December 21, 2008 - December 22, 2008 作者:  Zhang, Qiu-Yu;  Zhang, Mo-Yi;  Hu, Jian-Qiang 收藏  |  浏览/下载：7/0  |  提交时间：2020/11/15 Color  Gesture recognition  Object tracking  Probability distributions  Accurate location  Complex background  Frame difference methods  Moving informations  Probability modeling  Segmentation and tracking  Size and position  Skin-color information   Face detection based on template matching and 2DPCA algorithm 会议论文 作者:  Wang, Jizeng;  Yang, Hongmei 收藏  |  浏览/下载：2/0  |  提交时间：2019/11/15 face recognition  face detection  template matching  2DPCA
