Abstract

We review methods for kinematic tracking of the human body in video. The review is part of a projected book that is intended to cross-fertilize ideas about motion representation between the animation and computer vision communities. The review confines itself to the earlier stages of motion, focusing on tracking and motion synthesis; future material will cover activity representation and motion generation. In general, we take the position that tracking does not necessarily involve (as is usually thought) complex multimodal inference problems. Instead, there are two key problems, both easy to state. The first is lifting, where one must infer the configuration of the body in three dimensions from image data. Ambiguities in lifting can result in multimodal inference problem, and we review what little is known about the extent to which a lift is ambiguous. The second is data association, where one must determine which pixels in an image Full text available at: http://dx.doi.org/10.1561/0600000005

人体运动的计算研究:第1部分，跟踪和运动合成

本文综述了视频中人体运动跟踪的方法。这篇评论是一本计划出版的书的一部分，这本书的目的是在动画和计算机视觉社区之间交流关于运动表示的想法。回顾仅限于运动的早期阶段，专注于跟踪和运动合成;未来的材料将涵盖活动表示和运动生成。一般来说，我们认为跟踪并不一定涉及(通常认为的)复杂的多模态推理问题。相反，有两个关键问题，都很容易说明。第一种是升降，必须从图像数据中推断出物体的三维结构。举的模糊性会导致多模态推理问题，我们回顾了关于举的模糊性的程度所知甚少。第二个是数据关联，其中必须确定图像中的哪些像素全文可在:http://dx.doi.org/10.1561/0600000005

期刊介绍： The growth in all aspects of research in the last decade has led to a multitude of new publications and an exponential increase in published research. Finding a way through the excellent existing literature and keeping up to date has become a major time-consuming problem. Electronic publishing has given researchers instant access to more articles than ever before. But which articles are the essential ones that should be read to understand and keep abreast with developments of any topic? To address this problem Foundations and Trends® in Computer Graphics and Vision publishes high-quality survey and tutorial monographs of the field. Each issue of Foundations and Trends® in Computer Graphics and Vision comprises a 50-100 page monograph written by research leaders in the field. Monographs that give tutorial coverage of subjects, research retrospectives as well as survey papers that offer state-of-the-art reviews fall within the scope of the journal.
