To enable real-time, person-independent 3D registration from 2D video, we developed a 3D cascade regression approach in which facial landmarks remain invariant across pose over a range of approximately 60°. From a single 2D image of a person's face, a dense 3D shape is registered in real time for each frame. The algorithm utilizes a fast cascade regression framework trained on high-resolution 3D face-scans...
This paper describes a new approach for image-based modeling based on thermographic images and applied to efficiency energy studies of building façades. The approach is automatic and allows obtaining thermographic 3D models and orthoimages, which can be used to assess energy efficiency of building façades. The classical photogrammetry approach is reinforced and combined with computer vision algorithms,...
