摘要

视频镜头边界检测是一个被提出了许多技术和方法的领域,并声称在不同体育赛事的电视转播、谈话节目和新闻电视转播等视频中表现一致。电影中包含了大量任意变化的视觉信息;它需要一个高度有力的程序自动射击边界检测。本研究的主要目标是开发一种自适应和鲁棒的电影视频分割和分类算法。本文提出了一种完全自适应的镜头边界检测方法,该方法根据信息的变化改变阈值。我们定义了一种新颖的特征,它可以唯一地定义帧的颜色以及边缘和频率细节。它不仅能够检测到像硬切这样的突然转变,还能够检测到不同电影中的擦除、淡出和溶解等特效。

An adaptive novel feature based approach for automatic video shot boundary detection
The video shot boundary detection is an area, where many techniques and methods have been suggested and have claimed to perform consistently on the videos like television broadcasting of different sports events, talk shows & news telecast. The movies contain a large amount of visual information varying in arbitrary manner; it requires a highly vigorous procedure for automatic shot boundary detection. The main goal of this research is to develop an adaptive & robust algorithm for segmentation & classification of movie videos. In this paper, we described a novel approach for shot boundary detection which is totally adaptive & changes the threshold value as per the information change. We have defined the novel feature which can uniquely define color as well as edge & frequency details of a frame. It is able to detect not only abrupt transitions like hard cuts but also special effects like wipes, fades, and dissolves as well in different movies.
