| Abstract_FL | To solve the problem of unclearness of traffic surveillance video image in foggy days,the paper puts forward a fog removal system in traffic surveillance video image based on FPGA.Firstly,cacheing the collected real-time image data to SDRAM,then estimating the spreading images by using the luminance component,finally recovering the original explicit images based on the atmospheric scattering model.With the characteristics of powerful process ability and richful logic resource of FPGA,the processing speed of image is 60 frames per second for a 640×480 PAL corlor image.The result shows that the system can better remove the fog in video image on the premise of outputing a high qualified vedio image. |
