This paper presents a 3D path planning approach for UAV navigation given a mission task specified by a sequence of midway points and required orientation at each point. The approach developed was inspired by the Dubins 2D airplane algorithm. To avoid the difficulty of direct extension to 3D, the heading adjusting is undertaken in horizontal 2D plane at different altitude and the z motion is applied...
Based on zero-block detection method in H.264/AVC, the directional characteristic of the SAD(Sum of Absolute Differences Distortion), the centre-biased characteristic of motion vectors, and by analyzing the characteristics of OCTBS(Octagon-based Search), MOCTBS (Modified Octagon-based Search) algorithm is proposed in this paper. Firstly, MOCTBS employs small octagon pattern to judge if the MBD (Minimum...
