| Abstract: | To absolve image blur for high speed camera, fixed-point DSP TMS320C6416 and wiener filtering algorithm were adopted. Degeneration model for moving blur was researched. The principle of Wiener filtering was explained. FFT of 32bit was completed and DMA function of DSP to enhance processing speed was exerted. Ringing effect and edge effect were analyzed. The test results were presented. |
