“…Its effect is visible in our profile as tilt changes during panning, translation, and zoom. Minor flow can be kept in the profile to reflect the dynamics of the camera, or can be removed by a video deshaking algorithm before and after profiling [10,11,12]. The unstable motion, r, is from the instantaneous camera rolling, as well as the motion of dynamic targets against the background (BG) including non-rigid articulate motions and the deformation of human body and face, fire, smoke, water, etc.…”

“…In contrast, the temporal indexing, though under the controlled camera motion, has good results on camera rotation and translation by fixed [7,8] and dynamic slit scanning [9]. The shortcomings are (1) low temporal resolution for a short clip with fast motion; (2) views with a different projection from perspective projection; (3) deshaking of video or post smoothing [10,11,12].…”

This work takes a new aspect view to profile a video volume to a video track as a digest for video preview. Our projected video profile contains both spatial and temporal information inclusively in a 2D image scroll that is continuous, compact, scalable, and indexing to each frame. To profile various types of video clips, we investigate the global flow field under all camera actions, and propose a uniformed scheme that uses a sampling line to cut the video volume across the major optical flow field. The resulting profile obtains an intrinsic scene space less influenced by the camera actions, and can be displayed in a video track to guide the access to video frames, and facilitate video browsing, editing, and retrieval.
