Abstract:Describes the intelligent traffic lights based on video surveillance,which are consisted of the video acquisition,image processing and control module.The video image is acquired by the FPGA controlled imaging sensor,and analyzed by DSP in real-time online.In the image processing,Kalman Filter is adopted to renew the image background while OTSU algorithm is used to get the foreground data of the difference image.Finally,fuzzy algorithm is selected to forecast the later time's traffic flow to response the tra...
Keywords:traffic light  video capture  Kalman filter  neural network
