摘要
对视频图像进行语义信息的提取,可以满足用户基于语义的检索需求。在现有的一些语义信息提取方法中,存在如下问题:(1)如何构建合理的语义概念层次;(2)如何有效地表征视频图像所涉及的语义概念;(3)如何自动发现语义概念间的关联性并加以利用;(4)如何动态地融合语义信息;(5)如何挖掘视频在时域上的依赖信息并加以利用。针对上述问题,本文提出了三种方法,从不同层面分别进行解决。
     首先,本文提出一个自底向上的层次化语义提取框架。这个框架将视频镜头的底层特征、语义概念中的物体和语义概念中的场景划分为由底向上的三个层次。这个层次结构简单,也具有较好的表征能力。视频镜头的底层特征是在对视频镜头关键帧分割后的区域上提取的。针对每一种底层特征和每一个物体概念,训练得到的支持向量机,用本文提出的boosting方法,在不同特征上进行融合,得到了针对显著物体的检测器。本文提出了两种利用这些检测器的置信度输出,对视频镜头进行语义表征的模型向量,并在这两种模型向量的基础上对场景概念进行学习。实验证明本文的语义概念层次的有效性、boosting融合对性能的提升以及所提出的模型向量的优势。
     接下来,对于半自动的图像标注,本文将它形式化为一个多标记学习问题,并提出了一个基于辅助标签的半自动图像标注方法。该方法将归一化互信息作为定量地衡量语义标签之间关联度的指标,并采用一种动态混合模型改善标签的分类结果。该方法具有一个框架性的结构,很容易与标签的相关反馈信息结合,加速人机交互过程。实验结果表明该方法可以改善不同学习算法的分类结果,而且能够更有效地利用相关反馈信息,具有比其他方法更快的人机交互速度。
     最后,本文挖掘视频镜头在时域和空域上的关联信息,寻找同一镜头和相邻镜头中有助于一个目标物体检测的辅助物体,并确定这些辅助物体能够提供最大辅助信息的位置,这些辅助信息在一个动态混合模型中被整合,提高了原来的视频镜头中的物体检测性能。
The extraction of semantic information from videos and images can implement theretrieval based on the semantics. There are some issues in the existing extraction methods:(1) how to construct a sound semantic hierarchy; (2) how to effectively expressthe semantics; (3) how to automatically discover and utilize the relevance between semantics;(4) how to dynamically fuse the semantics; (5) how to mine and utilize thetemporal dependency of videos. Three methods are proposed to solve these issues.
     First, a bottom-up hierarchical semantics extraction framework is proposed, whichdivide the low-level features of shots, objects and scenes concepts into a bottom-upthree-level hierarchy. A support vector machine(SVM) is trained for a given low-levelfeature and a given object concept. The proposed boosting fusion, combines severalSVMs trained on each feature into a salient object detector. The confidence output ofthese detectors are used by two proposed model vectors to express the semantics ofshots. Scene concepts are then learned on these model vectors.
     Secondly, a semi-automatic image annotation method based on auxiliary tags isproposed, which measures the relevance between tags by the normalized mutual information,and improve the tag classification with a dynamic mixture model. This methodcan be easily combined with the relevance feedback on tags to speed up the interactionbetween human and the computer.
     Finally, to improve the object detection in video shots, spatial and temporal informationare further mined to discover and locate the helpful objects in the same shot orthe adjacent shot. These spatial and temporal auxiliary information are integrated in adynamic mixture model and improve the original detection results effectively.
