Abstract
A video condensation & recognition method and a system thereof are used to detect objects in input frames, derive a 3D object trajectory from which one or multiple 2D trajectories with object tubes are extracted, and catch a time position that refers to non-overlapping condition of object tubes for rearrangement of several continuous object tubes and creation of a condensed video. The generated condensed video can be adjusted by the user in the range of longest detected object tube to the generated condensed video length that is very beneficial for video analysis process. Moreover, a searched attribute of an object in a condensed video is classified for the filtering process which is able to display an object correlated with a distinct searched attribute on the condensed video.
