Human detection by searching in 3d space using camera and scene knowledge
Many existing human detection systems are based on sub-window classification, namely detection is done by enumerating rectangular sub-images in the 2D image space. Detection rate...

Quasi-Dense 3D Reconstruction using Tensor-based Multiview Stereo
We propose tensor-based multiview stereo (TMVS) for quasi-dense 3D reconstruction from uncalibrated images. Our work is inspired by the patch-based multiview stereo (PMVS), a stat...

Determining Characteristic Views of a 3D Object by Visual Hulls and Hausdorff Distance
Nowadays, with the exponential growing of 3D object representations in private databases or on the web, it is all the more required to match these objects from some views. To impr...

Picking and Snapping for 3D Input Devices
A picking mechanism (pointing and indicating) with the cursor is essential for any direct-manipulation application. The windowing systems, under which control a direct-manipulation...

Automatic 3D Reconstruction for Face Recognition
An analysis-by-synthesis framework for face recognition with variant pose, illumination and expression (PIE) is proposed in this paper. First, an efficient 2D-to-3D integrated fac...
