| Abstract: | We proposed an embedded system hardware implementation scheme for rice appearance detection video processing by using a multimedia image processor TMS320DM643 of TI company as the kernel processor. Firstly,the read-back images of a rice sample video system were respectively simulated by using Sobel operator and the improved algorithm thereof based on the MATLAB platform.The simulation results showed that the improved algorithm could detect more intact rice edge.Then,the improved Sobel edge detection algorithm was selected in the hardware system to achieve the real-time detection of the rice video images,wherein one frame of the image could be processed in only 42.7 ns. |
