摘　　要：目前市场上支持视频图像处理功能的软件虽然多种多样,但通常涉及行业背景,应用范围狭窄,开放的视频图像处理组件在容错或安全性上表现一般,因此有必要创新和开发特定功能的视频处理组件。该设计基于Direct Show架构,开发出具有视频处理功能的Filter组件,具有本地图片叠加入视频流、视频编码格式转换、截取画面保存为本地图像等功能。可在视频图像传递过程中对图像进行实时处理、添加信息、优化或保存画面等,使人们以更加灵便的方式获取、使用或传播视频信息。测试结果表明,该组件可应用于广播电视传输或视频采集时的图像处理,甚至应用于美颜相机或PC摄像头的趣味叠图等,应用范围广泛,平台兼容性强,填补了市场上该类产品的类型和功能短缺。The software supporting video image processing function is various on the market,but it has narrow application range due to the industry background. And the opened video image processing module has poor performance on fault tolerant or security,so it is necessary to innovate and develop the video processing module with specific function. The Filter module with video processing function was developed based on DirectShow framework,which has the functions of local image added into video streaming,video coding format transform,and extracting frames saved as the local image. The module can realize the operations of real?time processing,information adding,frames optimization or frames preservation for the image in video image transfer pro?cess,so people can acquire,use or transmit video information with more flexible way. The test results show that the module can be applied to radio and television transmission or image processing while video collection,and beauty camera or funny overlay of PC camera. The module has wide application range and good platform compatibility,which filled the type and function shortage of this product on the market.
