IEEE Transactions on Circuits and Systems for Video Technology, 2012
This paper presents an improved hand tracking system using pixel-based hierarchical-feature AdaBoosting (PBHFA), skin color segmentation, and codebook (CB) background cancellation. The proposed PBH feature significantly reduces the training time by a factor of at least 1440 compared to the traditional Haar-like feature.

Hand tracking with physiological constraints
The Visual Computer, 2016Articulated hand tracking systems have been commonly used in virtual reality applications, including systems with human–computer interaction or interaction with game consoles; hand pose estimation has various other applications comprising sign language recognition and animation synthesis.

2011 18th IEEE International Conference on Image Processing, 2011
This study presents a hybrid hand tracking system using Pixel-Based Hierarchical-Feature AdaBoosting (PBHFA), skin color segmentation, and codebook background cancellation. The object of this approach is to construct a system which is able to cope with hand detection and further tracking tasks.

Visual Hand Tracking Algorithms
Geometric Modeling and Imaging--New Trends (GMAI'06), 2006Tracking is an important section in a gesture recognition system. Numerous techniques for segmentation, tracking, modeling and recognition have been proposed during several past years. A few papers comparing different approaches have been published [31,32]. However, a comprehensive survey on tracking is still missing.

Hand tracking in bimanual movements
Image and Vision Computing, 2005A general hand-tracking algorithm is presented for tracking hands in bimanual movements. The problem is approached from a neuroscience point of view. Using a dynamic model and some motor control phenomena, the movement of the hands during a bimanual movement is recognised.

From Hand to Hand : Tracking the Workflow of Kassite Officials
Mesopotamia : rivista di archeologia, epigrafia e storia orientale antica : LVIII, 2023, 2023Cuneiform tablets from Kassite Babylonia record the names of thousands of individuals who interacted at different levels with the institutions that produced these texts. A useful criterion to recognize, among them, those who had an active role in the resource management is looking for personal names that follow the term “hand” (Akk.

Hidden Hands: Tracking Hands with an Occlusion Aware Tracker
2016 IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2016This work presents an occlusion aware hand tracker to reliably track both hands of a person using a monocular RGB camera. To demonstrate its robustness, we evaluate the tracker on a challenging, occlusion-ridden naturalistic driving dataset, where hand motions of a driver are to be captured reliably.

Recognizing and tracking clasping and occluded hands
2013 IEEE International Conference on Image Processing, 2013We present a purely algorithmic method for distinguishing when two hands are visually merged together and tracking their positions by propagating tracking information from anchor frames in single-camera video without depth information. We demonstrate and evaluate on a manually labeled dataset selected primarily for clasped hands with 698 images of a ...

Template-Based Hand Detection and Tracking
2005Within this paper a technique for model-based 3D hand tracking is presented. A hand model is built from a set of truncated quadrics, approximating the anatomy of a real hand with few parameters. Given that the projection of a quadric onto the image plane is a conic, the contours can be generated efficiently.

Acoustic tracking of hand activities on surfaces
Proceedings of the 2nd international Workshop on Sensor-based Activity Recognition and Interaction, 2015Many common forms of activities are tactile in their nature. We touch, grasp, and interact with a plethora of objects every day. Some of those objects are registering our activities, such as the millions of touch screens we are using every day. Adding perception to arbitrary objects is an active area of research, with a variety of technologies in use ...
