Egocentric Basketball Motion Planning from a Single First-Person Image Gedas Bertasius, Aaron Chan and Jianbo Shi CVPR 2018 [MIT SSAC Poster]    Am I a Baller? Spatiotemporal information is essential for video salient object detection (VSOD) due to the highly attractive object motion for human's attention. Click to go to the new site. The major concern of constructing a 3D video object detector is how to model the spatial and temporal feature representation for the consecutive point cloud frames. This naturally renders the approach robust to occlusion or motion blur in individual frames. However, a point cloud video contains rich spatiotemporal information of the foreground objects, which can be explored to improve the detection performance.
