Background The study of human movement within sports biomechanics and rehabilitation
settings has made considerable progress over recent decades. However, developing a …

This review article surveys extensively the current progresses made toward video-based
human activity recognition. Three aspects for human activity recognition are addressed …

Human motion analysis is receiving increasing attention from computer vision researchers.
This interest is motivated by a wide spectrum of applications, such as athletic performance …

A comprehensive survey of computer vision-based human motion capture literature from the
past two decades is presented. The focus is on a general overview based on a taxonomy of …

The ability to recognize humans and their activities by vision is key for a machine to interact
intelligently and effortlessly with a human-inhabited environment. Because of many …

Visual analysis of human motion is currently one of the most active research topics in
computer vision. This strong interest is driven by a wide spectrum of promising applications …

In free-viewpoint video, the viewer can interactively choose his viewpoint in 3-D space to
observe the action of a dynamic real-world scene from arbitrary perspectives. The human …

We present a vision system for the 3-D modelbased tracking of unconstrained human
movement. Using image sequences acquired simultaneously from multiple views, we …

This paper describes a probabilistic decomposition of human dynamics at multiple
abstractions, and shows how to propagate hypotheses across space, time, and abstraction …

This paper presents an approach for viewpoint invariant human action recognition, an area
that has received scant attention so far, relative to the overall body of work in human action …
