A method for the collision avoidance of an articulated kinematic chain in a dynamic environment is presented. The inverse kinematic solution is used to get the configuration of the chain for a given position of any part of the chain. The calculation of collision-free motion is based on the local information about the motion. Intermediate positions are used(More)
Drift error is a critical issue in video scrambling which is widely used to protect privacy in surveillance video. However, how to improve video coding efficiency while preventing drift error in video scrambling has not been covered in most studies. Proposed is a prediction restricted scheme for H.264/AVC privacy protected video scrambling. Experiments show(More)
