摘要
智能交通控制系统中,针对车辆图像信息的传输技术过于消耗网络带宽的现状,给出了一种基于双正交小波的运动车辆图像压缩的方法。通过将每帧图片进行小波变换,只传输小波变换后的系数,且此系数包含了图像的大部分信息,大大减少了图像数据的传输流量,提高了控制系统的效率。最后对文中方法进行MATLAB仿真测试,并且与基于DCT的JPEG图像压缩方法进行了比较。
In the research of intelligent traffic control system,the vehicle image information transmission technology is over consumption status of network bandwidth. This paper gives out a method to solve the problem which is based on Biorthogonal wavelet. Each frame image transformed by wavelet,and the coefficients transformed by wavelet can be transferred only and the coefficient contains most of the information of the image,greatly reduces the flow of image data transmission,improves the efficiency of the control system. Finally,it presented the MATLAB simulation test of this method,and compared with the JPEG image compression method based on DCT.
