Abstract: Aiming at the problem that the traditional noise reduction is difficult to deal with real-time in industrial detection, a real-time dynamic video noise reduction method based on the DirectShow was proposed. Using the DirectShow technology, a platform for video editing was built, adopting the noise reduction algorithm of lifting scheme to set up the Videos Filter. This method was realized by the software, and it reduced the costs and avoided the use of specific hardware restrictions. The simulation results showed that this method had better real-time ability and noise reduction effect.
