摘要

随着数字视频技术的发展和计算结果的可及性不断提高,视频镜头自动检测受到了很大的影响。本文描述了一种利用原始视频帧的不同统计特征的阈值提取镜头检测的框架。两种不同类型的体育视频即足球和篮球被用于评估。该方法利用相关性、最大直方图差和运行平均差作为分类器。在对框架进行训练后,通过选择合适的阈值对结果进行评估。当相关系数和直方图差分特征无法识别镜头检测时,采用赢家通吃的选择方案。在发散集测试视频上的实验结果表明了该方法的有效性。

A novel framework of shot boundary detection for uncompressed videos
The automatic video shot detection is receiving a great impact with the advances in the digital video technology and ever increasing accessibility of computing results. In this paper we describe a framework for extracting shot detection by using the threshold values of diverse statistical features for raw video frames. Two different types of sports videos viz. soccer and basketball are used for assessment. The approach exploits correlation, maximum histogram difference and running average difference as the classifiers. The results are evaluated by selection of appropriate threshold of these features after training of framework. The winner take-all selection scheme is applied if correlation coefficient and histogram difference features are unable to identify the shot detection. Experimental results on divergent set of test videos reveal the effectiveness of this shot detection approach.
