Is video segmentation a standalone problem?How about recognition and reconstruction?(Vittorio and Cristian)

What subtasks should we evaluate on?general tasks, motion subtask, object proposals, superpixels,high precision (cf. Adobe needs us!)(Jue and Ren)8First International Workshop on Video Segmentation | Remarks8
