Detecting Anchorperson Frame from the News Video Using the Matching of Dominant Color Template

  • 摘要: 检测新闻主持人口播帧是定位和分割新闻单元的有效途径,利用主色模板匹配检测口播帧的方法首先提取口播帧的主色模板,然后利用该模板对新闻视频的帧序列进行匹配,并由计算机自动对口播帧进行检测和标识 该检测方法与现有的检测方法相比,具有设计简单、计算量小、速度快的特点,并通过实验证明其具有较高的检出率和准确率.

     

    Abstract: In order to detect the anchorperson frame from the news video, a completely new method, the matching of dominant color template, is proposed in the paper. By the method, firstly the dominant-color template is extracted from the anchorperson frame, and then the computer could automatically detect and mark the anchorperson frame through matching the dominant color of each frame with the template. Compared with the existing detection methods, the proposed method is very easy to design and is able to run completely in real time. The experimental results show that the method is efficient and accurate.
