| Abstract: | The image processing unit is key to the precision and timeliness of the moving target tracking system.The system collects the dynamic image and preprocesses it,then sends the results to the image processing unit to accomplish the operation of median filter,edge detection and match tracking.The paper introduces an improved median filter algorithm and a novel edge detection algorithm based on Sobel algorithm.After manipulated as above,the image processing unit decreases the times of operation and offers faster processing speed. |
