Haarlet-based hand gesture recognition for 3D interaction
(2009)2009 Workshop on Applications of Computer Vision (WACV)This paper presents a system to manipulate 3D objects or navigate through 3D models by detecting the gestures and the movements of the hands of a user in front of a camera mounted on top of a screen. This paper more particularly introduces an improved skin color segmentation algorithm which combines an online and an offline model; and a Haarlet-based hand gesture recognition system, where the Haarlets are trained based on Average Neighborhood ...Conference Paper -
Multi-view traffic sign detection, recognition, and 3D localisation
(2009)2009 Workshop on Applications of Computer Vision (WACV)Several applications require information about street furniture. Part of the task is to survey all traffic signs. This has to be done for millions of km of road, and the exercise needs to be repeated every so often. A van with 8 roof-mounted cameras drove through the streets and took images every meter. The paper proposes a pipeline for the efficient detection and recognition of traffic signs. The task is challenging, as illumination ...Conference Paper -
A comparison of 3d model-based tracking approaches for human motion capture in uncontrolled environments
(2009)2009 Workshop on Applications of Computer Vision (WACV)This work addresses the problem of tracking humans with skeleton-based shape models where video footage is acquired by multiple cameras. Since the shape deformations are parameterized by the skeleton, the position, orientation, and configuration of the human skeleton are estimated such that the deformed shape model is best explained by the image data. To solve this problem, several algorithms have been proposed over the last years. The ...Conference Paper -
Moving obstacle detection in highly dynamic scenes
(2009)2009 IEEE International Conference on Robotics and AutomationWe address the problem of vision-based multi-person tracking in busy pedestrian zones using a stereo rig mounted on a mobile platform. Specifically, we are interested in the application of such a system for supporting path planning algorithms in the avoidance of dynamic obstacles. The complexity of the problem calls for an integrated solution, which extracts as much visual information as possible and combines it through cognitive feedback. ...Conference Paper
