In this paper, a global optimum stereo matching algorithm based on improved belief propagation is presented which is demonstrated to generate high quality results while maintaining real-time performance. These results are achieved using a foundation based on the hierarchical belief propagation architecture combined with a novel asymmetric occlusion handling(More)
—Current active 3D range sensors, such as time-of-flight cameras, enable acquiring of range maps at video frame rate. Unfortunately , the resolution of the range maps is quite limited and the captured data are typically contaminated by noise. We therefore present a simple pipeline to enhance the quality as well as improve the spatial and depth resolution of(More)

Capturing realistic 3D shapes of human bodies is very useful for many computer graphics applications. However, for existing 3D shape capturing devices, such as structured light, laser scanner or multi-view methods, problems arise when dealing with 3D hairstyle scanning and body deformation. To solve these problems, a novel approach is proposed to scan 3D(More)
