Method of Normalized Frame Difference of Gray Distribution for Video Shot Detection

研究视频检索中的镜头突变检测问题,分析造成镜头突变检测中出现误检的原因,提出一种鲁棒的、适用于自适应阈值突变镜头检测方法的规范化灰度分布帧差的定义。实验表明,当视频图像中噪声较低时,采用规范化灰度分帧差定义,应用自适应取阈值的检测方法,对视频中镜头突变的检测有较高的准确率。

This paper researches the shot detection of the video indexing problem, analyzes the cause of the error detections of shots, presents a new robust method based on normalized frame difference of gray distribution for shot detection with adaptive threshold. Experiment results demonstrate that it achieves high accuracy for shot detection with adaptive threshold.
