On the premise that cameras have uniform motion  restoration model for moving blurred image was researched  the principle of Wiener filtering is explained  the key technologies of moving blurred image restoration with TMS320C6416 are introduced: how to complete FFT calculation of 32bit and how to exert DMA function of DSP to enhance processing speed  ring effect and ghost effect in restored image are explained  and how the parameter of wiener filter affects ring effect and ghost effect is discussed  in addition to this  other reasons of ring effect and ghost effect are analyzed detailed. Experiments shows that One TMS320C6416 chip can restore seven frames per second  there is great hope to realize real-time restoration if adopting multi-DSP or the FFT completion by hardware.   Realization of electron image stabilization based on TMS320C6416 (EI CONFERENCE) 会议论文  OAI收割 Proceedings of the Sixth IEEE CPMT Conference on High Density Microsystem Design and Packaging and Component Failure Analysis, HDP'04, June 30, 2004 - July 3, 2004, Shanghai, China 作者:  Yao Z.-J.;  Liu W. 收藏  |  浏览/下载：18/0  |  提交时间：2013/03/25 To absolve image blur of high speed camera  ringing effect and edge effect are analyzed  fixed-point DSP TMS320C6416 and wiener filtering algorithm are adopted. Degeneration model for moving blur is researched  the principle of Wiener filtering is explained: how complete FFT of 32bit and how to exert DMA function of DSP to enhance processing speed  and the test results are presented. 2004 IEEE.
