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.   Analysis and design of No-Reference Image Quality Assessment (EI CONFERENCE) 会议论文 2008 International Conference on MultiMedia and Information Technology, MMIT 2008, December 30, 2008 - December 31, 2008, Three Gorges, China Tian Y.; Zhu M.; Wang L. 收藏  |  浏览/下载：9/0  |  提交时间：2013/03/25 No-Reference (NR) Image Quality Assessment (IQA) seeks to assign quality scores that are consistent with human perception but without an explicit comparison with the reference image. Unfortunately  the field of NR IQA has been largely unexplored. The basic problems in NR IQA are discussed in this paper. and several methods used in NR IQA are explained and analyzed. Finally  an overall NR IQA method is designed. It should be a synthetical index  which applying fuzzy measures and fuzzy integrals  incorporating Human Vision System (HVS) characteristics and adhering to the philosophy of quantifying quality through blind distortion measurement. 2008 IEEE.
