[Topic] Holistic Video Understanding
We address the problem of multiclass semantic video segmentation, aiming to integrate object reasoning, scene layout estimation with pixel labeling. To this end, we have developed an object-augmented structured model in spatio-temporal domain, which captures long-range dependency between superpixels, and imposes consistency between object and superpixel labels. We also designed an efficient inference algorithm to jointly infer the superpixel labels, object activations and their occlusion relations for a large number of object hypotheses.
