摘　　要：在工业检测中,针对传统的降噪方法难以实时处理的问题,提出了一种基于DirectShow的实时处理视频的动态降噪方法。利用DirectShow技术建立视频编辑平台,采用提升框架的降噪算法建立视频处理的滤波技术。该方法用软件实现,降低了成本,避免了使用特定硬件的限制,易于修改。仿真结果表明,该方法具有较好的实时性和去噪效果。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.
