Monocular and Binocular Visual Tracking
Visual tracking is one of the most important applications of computer vision. Several tracking systems have been developed which either focus mainly on the tracking of targets moving on a plane, or attempt to reduce the 3-dimensional tracking problem to the tracking of a set of characteristic …

Visual tracking of highly articulated objects using massively parallel processors
… analysis by synthesis approach to this difficult tracking problem. We attempt to overcome the vast amount of computation required by implementing the algorithm on commodity GPUs. We also collect a lengthy sequence of hand motions from five cameras in order to train and test our algorithm. We show …

Implementation of coarse-to-fine visual tracking on a custom computing machine
“Smart” surveillance systems require a visual tracking system that is able to detect and follow a moving target in the field of view of a camera. Visual tracking systems have been traditionally developed either as application specific hardware or as software written for parallel architectures …

Coping with uncertain dynamics in visual tracking : redundant state models and discrete search methods
… of the world dynamics is a vital part of any tracking algorithm. The observed world can exhibit multiple complex dynamics at different spatio-temporal scales. Faithfully modeling all motion constraints in a computationally efficient manner may be too complicated or completely impossible. …

Acoustic and visual tracking reveals distribution, song variability and social roles of humpback whales in Hawaiian waters
Acoustic and visual methods were used to track and observe humpback whales off Hawai'i. Chapter 3 found 62 singing whales were located acoustically in water depths from 10 to 305 fathoms. This indicates that singers are not confined within the 100 fathom contour, although near shore waters had a …

High-performance Object Detection and Tracking Using Deep Learning
Human detection and tracking are two fundamental problems in computer vision, which have been cornerstones for many real-world applications such as video surveillance, intelligent transportation systems and autonomous driving. Benefiting from deep learning technologies such as convolutional neural …

Using colour features to classify objects and people in a video surveillance network
Visual tracking of humans has proved to be an extremely challenging task for computer vision systems. One idea towards a development of these systems is the incorporation of colour. Often colour appearance of a person can provide enough information to identify an object or person in the short-term. …

People Tracking Under Occlusion Using Gaussian Mixture Model and Fast Level Set Energy Minimization
Tracking multiple articulated objects (such as a human body) and handling occlusion between them is a challenging problem in automated video analysis. This work proposes a new approach for accurately and steadily visual tracking people, which should function even if the system encounters occlusion …

Fusion of non-visual and visual sensors for human tracking
"Human tracking is an extensively researched yet still challenging area in the Computer Vision field, with a wide range of applications such as surveillance and healthcare. People may not be successfully tracked with merely the visual information in challenging cases such as long-term occlusion. …

Graphical models for visual object recognition and tracking
… statistical methods which allow effective visual detection, categorization, and tracking of objects in complex scenes. Such computer vision systems must be robust to wide variations in object appearance, the often small size of training databases, and ambiguities induced by articulated or …

Fixed-wing Classification through Visually Perceived Motion Extraction with Time Frequency Analysis
… Monitoring solutions such as drone detection, tracking, and classification become increasingly important to maintain compliance for regulatory and security purposes, as well as for recognizing aircraft that may not be so. Vision systems offer significant size, weight, power, and cost (SWaP-C) …
