Research highlights ► We apply intensity and depth data acquired by a Time-of-Flight sensor. ► Gestures are represented efficiently using 3D optical flow and motion context. ► We show how a motion context can be made view-invariant using spherical harmonics. ► We address the problem of...
Research highlights ► Time-of-flight range map and intensity image are linked by shading constraint. ► Shading constraint can be exploited to improve accuracy of range map. ► Algorithm can handle surfaces with varying albedo.
Research highlights ► SfS reconstruction with color cameras is difficult due to false foreground detections. ► ToF camera range images provide simple and robust foreground segmentation. ► Using a ToF camera with color cameras constrains the SFS result and eliminates defects.
Research highlights ► An algorithm to detect the tip of the nose in TOF range data. ► It is relevant for real-time tracking and pose estimation. ► Finding features on a large range of pose angles.
Research highlights ► 3D human pose estimation from depth image streams. ► Key feature point detection based on a probabilistic inference algorithm. ► Real time reconstruction of 3D human pose from low dimensional key feature points. ► Model based constrained inverse kinematics...
Research highlights ► Integrated method for post-processing of range and color images. ► Based on the non-local principle adapted to characteristics of typical depth data. ► Denoising approach achieves unbiased reconstructions from error-prone input data. ► Reconstruction of strong...
Research highlights ► Discussion of TOF-camera related error sources. ► Decoupled calibration model for intensity-related distance deviations. ► Combined calibration model for intrinsic, distance and intensity calibration.
