METHOD AND DEVICE FOR GENERATING VIDEO ABSTRACT

摘要

A method and device for generating a video abstract are provided in the present invention. The method comprises: dividing an original video into multiple fields of view; classifying each object track comprised in the original video to a field of view which is closest to the object track based on approach degree between the object track and each field of view; counting activity degree index of the field of view based on activity degree of the object track in the field of view, and dividing each field of view into an important field of view and a subordinate field of view according to whether the activity degree index exceeds a preset threshold or not; processing object tracks in each important field of view and subordinate field of view in parallel and combining each one of the obtained field of view after parallel processing to generate a video abstract. In the method for generating the video abstract in the present invention, by parallel processing on object tracks in important fields of view and subordinate fields of view, calculation amount on track combinations is reduced, calculating speed is increased, and the user can focus on the main objects in the important fields of view straightforwardly.
