Abstract

The implementation of the invention discloses an adaptive football video summary generation method, receiving the football video streaming using shot boundary detection method based on the average sliding window frames to do shot boundary detection in football video streams to get the video sets; use video classification method based on sub lens region to classify the video sets; do wonderful video detection in the classified video sets and output the detected wonderful video as video summary. The invention also discloses an adaptive football video summary generation device, which can improve the efficiency and accuracy of football video summary generation.

Description

technical field [0001] The invention relates to video abstract generation technology, in particular to a method and device for adaptively generating football video abstracts. Background technique [0002] At present, the development of multimedia, digital TV and network technology produces a large number of video files, how to effectively manage these video files and how to realize fast browsing has become an urgent problem to be solved. Because football is widely concerned by people, the management and retrieval of football videos has become an important aspect of sports video research. Due to the particularity of football video, its processing method is also different from that of general news video and movie video. In a nutshell, the techniques for football video processing mainly include shot boundary detection, shot classification, slow motion detection, extraction of highlights, stadium scene reconstruction, event detection, and video summary generation. [0003] In ...
