From: A unified framework for spatiotemporal salient region detection
Examples of motion saliency detection. (a) A pedestrian under a static camera attracts attentions. (b) The camera is tracking a walking person, who attracts more attention. First column: sample frames of two videos. Second column: the corresponding optical flow. Third column: motion saliency map calculated with optical flow directly. Fourth column: motion saliency map calculated with HOAOF.
