The goal of this article is to review the state-of-the-art tracking methods, classify them into
different categories, and identify new trends. Object tracking, in general, is a challenging …

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 new approach toward target representation and localization, the central component in
visual tracking of nonrigid objects, is proposed. The feature histogram-based target …

A new method for real time tracking of non-rigid objects seen from a moving camera is
proposed. The central computational module is based on the mean shift iterations and finds …

Computer and Machine Vision: Theory, Algorithms, Practicalities (previously entitled
Machine Vision) clearly and systematically presents the basic methodology of computer and …

Automatic understanding of events happening at a site is the ultimate goal for many visual
surveillance systems. Higher level understanding of events requires that certain lower level …

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 …

As a step towards a perceptual user interface, an object tracking algorithm is developed and
demonstrated tracking human faces. Computer vision algorithms that are intended to form …

This work proposes a method to characterize the appearance of individuals exploiting body
visual cues. The method is based on a symmetry-driven appearance-based descriptor and a …

An algorithm for tracking a person's head is presented. The head's projection onto the image
plane is modeled as an ellipse whose position and size are continually updated by a local …
