	Real-time restoration for motion-blurred color images by multichannel combination processing (EI CONFERENCE) 会议论文 OAI收割 1st International Workshop on Education Technology and Computer Science, ETCS 2009, March 7, 2009 - March 8, 2009, Wuhan, Hubei, China 作者: Sun H.; Sun H.; Li S. 收藏 \| 浏览/下载：46/0 \| 提交时间：2013/03/25 A fast algorithm is proposed to restore the color images degraded in a deterministic way by motion- blurred by multichannel combination processing. Based on the color space conversion model the point spread functions of the image motion on each plane of YUV422 image can be achieved. The U V plane of YUV422 images are combined to form a new UV plane which has the same size as Y plane. Then the Y UV plane are packed into a two dimensional complex array which can be transformed directly by FFT and result a composite frequency spectrum. Wiener filter is applied to filter Y UV spectrums separated from the composite spectra. On Graphics Processing Unit (GPU) platform the proposed algorithm can restore a 1024x1024 24-bit motion-blurred color image in 7.95ms and the PSNR of the restored image is 27.12 which reveals a good restoration performance. 2009 IEEE.
	Study on the Driving Scheme of a 4-m Alt-azimuth Telescope (EI CONFERENCE) 会议论文 OAI收割 3rd International Symposium on Advanced Optical Manufacturing and Testing Technologies, AOMATT 2007: Large Mirrors and Telescopes, July 8, 2007 - July 12, 2007, Chengdu, China 作者: Zhang J.; Dai S.; Zhao Y.; Zhao Y.; Zhao Y. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 By summarizing the corresponding parameters Of the driving system of a 4-m Alt-azimuth telescope some unit techniques like the driving modes and structure angular position measurement methods in detail have been analyzed in the paper. A set of primary schemes for astronomical applications including the altitude axes being driven by 2 DC torque motors the azimuth by 4 DC torque motors using helical gears and two pieces of the 27-bit segment tape encoders for each set of axes is proposed. To meet practical engineering needs the shafting motion parameters are designed and motor elementary parameters are primarily calculated to offer the important references for further study on system driving model and prototype development.
