| Abstract: | To study the problem of detecting and tracking fast-moving vehicles in complex circumstances,an adaptive algorithm for image segmentation and filtering was proposed using intelligent Agent based on knowledge database,and an adaptive background model was built through the dynamic matrix of accumulated frame differences.In the tracking process,an improved SSD(sum of squared differences) algorithm was designed to forecast the initial iteration points.According to the Jensen inequality,a MeanShift algorithm for... |
