Marker-less motion capture has seen great progress, but most state-of-the-art approaches fail to reliably track articulated human body motion with a very low number of cameras, let alone when applied in outdoor scenes with general background. In this paper, we propose a method for accurate marker-less capture of articulated skeleton motion of several subjects in general scenes, indoors and outdoors,...
We describe a system for content-based retrieval from large surveillance video archives, using behavior, action and appearance of objects. Objects are detected, tracked, and classified into broad categories. Their behavior and appearance are characterized by action detectors and descriptors, which are indexed in an archive. Queries can be posed as video exemplars, and the results can be refined through...
Given a set of 2D images, we propose a novel approach for the reconstruction of straight 3D line segments that represent the underlying geometry of static 3D objects in the scene. Such an algorithm is especially useful for the automatic 3D reconstruction of man-made environments. The main contribution of our approach is the generation of an improved reconstruction by imposing global topological constraints...
The multi-mission Dshell++ simulation framework has formed the basis for high-performance, physics-based simulations for a large variety of space mission simulations including cruise and orbiter spacecraft, Entry, Descent, Landing (EDL) missions as well as for planetary surface rovers. The Dspace interactive, reusable 3D visualization system has been developed to support the diverse visualization...
The paper proposes an independent component analysis approach specifically aimed at enhancing low-resolution text images from handheld devices. Three layered Independent components are extracted from the image, checked for the components if missing in any of the layer and then integrated so as the missing component can be mixed. Afterwards the image enhancement techniques such as threshold and dilation...
