摘　　要：经典的图像去噪方法如均值滤波和中值滤波,以及现在效果显著的小波去噪,在实际应用中都取得了令人满意的图像处理效果。但在视频应用中,这些算法只使用了空域信息,没有充分利用时域的信息,所以不能取得最佳效果。自适应的帧间滤波降噪方法,充分利用了视频的时域的信息,取得了比空域滤波器更好的效果。同时算法简单,图像处理的时间大为节省,便于在工程中应用。classic image denoise method includs low - pass filter, median filter and most effective wavelet denoise filter. These methods both have good effect in real world application. But in video denoise domain, these method only use special information and don＇t use time domain information. So this kind of filter wouldntt have best effects. This paper proposes an self - adaptive time domain filter which uses video sequencers time information. The new method has superior effect than all kinds of space domain filter. The method is quite simple and dontt need lots of CPU cycle and is easy to use in all kinds of application.
