| Abstract: | For the degradation of image sequence due to noise, the temporal noise filter is designed during video image acquisition process. The problem of the Kalman filering and the algorithm of the adaptive Kalman filtering are studied. And the predigestion of the adaptive Kalman filtering in the interest of hardware implementation is discussed,the predigestion arithmetic is imitated. The design of the adaptive temporal Kalman filter based on FPGA implementation has been achieved. |
