Temporal segmentation partitions video into shots based on similarity of frames. Spatial segmentation partitions each video frame into homogeneous regions, which can be achieved by segmenting each frame individually based on color similarity (intra-frame image segmentation). Spatio-temporal segmentation yields temporally connected spatial segments or object trajectories, for example, by inter-frame segmentation ...
