	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：45/0 \| 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.
