摘要

本文面向视频分析和索引技术

提出一种利用人物相似度进行视频索引的算法.该算法应用SVMs概率输出理论

将底层特征空间距离映射为语义层人物相似度

并提出一种新的非监督聚类算法

修正部分误判

最终实现对视频节目中人物的自动聚类和索引.实验结果表明

该算法实用而高效

是对现有视频索引算法的有效补充.

Abstract

This paper presents a novel approach to video indexing.In this approach

we define a people-similarity measure according to both clothing similarity and speaking voice similarity.Such similarity depicts how perceptually similar two people appearing in different scenes are and whether they belong to an identical person.The extended support vector machines are applied to map a serial of low-level feature distances to a perceived people-similarity.To build people-similarity based video indexing

a novel unsupervised clustering algorithm is also proposed

which can more correctly group individual person according to the mutual people-similarities among multiple people pairs.
