Semi-automatic tool for motion annotation on complex video sequences

摘要

Ground truth annotation on motion segmentation (MS) datasets of arbitrary real-life videos is a difficult and challenging task. The research community lacks a standard annotation tool for such datasets, which makes it an open research field. Here an annotation tool is proposed for trajectories in complex videos, which provides a publicly available platform to create and reinforce MS datasets. The user friendly interface allows to refine an initial automatic segmentation result to produce ground truth annotation on all the motions of all the frames of a given sequence. In long videos with multiple rigidon-rigid motions containing complete occlusion and real distortions, the tool facilitates rapid annotation of motion in a semi-automatic way.
