摘　　要：叙述了视频信号处理中的小波变换的应用。在介绍了视频采集系统基本结构和功能的基础上,首先叙述了用小波变换检测视频信号的各参数的方法,然后讨论了如何在具体设备当中实时实现小波变换,提出了用“双存储器”实现的方法。The application of wavelet transform in video signal processing is described. Based on introduction of the basic constitution and functions of video sampling system, the method for detecting various parameters of video signals by means of wavelet transform is first described, then how the wavelet transform is carried out in the concrete equipment is discussed, and the method for performing Dual RAM is proposed later.
