Abstract
Embodiments of the present invention provide a video synopsis method and apparatus, and relate to the field of video synopsis. The method includes: extracting moving objects and moving tracks of the moving objects from an original video; calculating a spatio-temporal redundancy between the extracted moving tracks, and determining a synopsis ratio of the moving tracks according to the spatio-temporal redundancy; and changing rates of the moving tracks according to the synopsis ratio of the moving tracks. In the present invention, the spatio-temporal redundancy between the moving tracks is analyzed, and synopsis and rate changing are performed on corresponding tracks according to the spatio-temporal redundancy obtained by means of analysis to obtain different representations of different tracks, thereby improving user experience.
