Under-water video-mosaics are an important tool e.g. for inspection of man-made infrastructure. Cameras may drift in rotation and distance to the surface while the mosaic will often be very much larger than a single frame resulting in long chains of planar homographies. This contribution addresses the problems arising from dead-reckoning drift in such chains. Local patches are rectified using homography...
In this paper, we address the problem of reconstructing 3D trajectories given only 2D point projection trajectories of an articulated structure. Hitherto, most applications of articulated trajectory reconstruction require: (i) relative lengths, and (ii) camera motion. We propose a novel extension that allows us to in many circumstances circumvent these limitations. Of particular note is our characterisation...
Any trajectory is always generated with its origin and destination. Origin-destination (OD) generation for trips plays an important role in many applications such as trajectory mining, traffic simulation, or marketing. In previous work on traffic pattern recognition, microscopic ODs for limited areas are estimated with probe-car data, while macroscopic ODs for broad areas are usually generated by...
