Mobile robot is commonly used for firefighting, medical treatment, housekeeping, etc. The first trouble we should solve is navigation, and the most important part of mobile robot navigation is 3D reconstruction, which is also main part of this paper. In this paper, we compare several common RGB-D devices including Microsoft Kinect, Intel RealSense R200, Asus Xtion PRO Live. Then two main methods of...
H.264/SVC is a promising coding standard in wireless transmission with scalable features. It can adapt video qualities to the unstable bandwidth. To optimize the receiving side's video quality for H.264/SVC transmission over wireless networks with package loss, a novel and simple loss impact estimation based automatic repeat request (ARQ) algorithm is proposed in this paper. The proposed ARQ algorithm...
To optimize the playback quality in H.264/SVC transmission, a distortion based selective packet discarding scheme for H.264/SVC is presented in this paper. The method can precisely discard the packets with lowest lost-impact if bandwidth is overloaded. Lost-impact of each packet is evaluated by our distortion estimating function which takes macroblock level information, temporal error propagation...
