Title: METHOD FOR ASSEMBLING TO-BE-DISPLAYED MOVING OBJECTS IN VIDEO FRAMES
Abstract:
The invention discloses a method for reasonably assembling to-be-displayed moving objects in video frames. The method comprises: first, taking the background of an original video as an initial frame of a video synopsis of the original video through a background modeling method, and finding a first to-be-displayed object from a to-be-displayed moving object set; second, placing the first to-be-displayed object into the video synopsis according to a moving trail of the first to-be-displayed object in the original video; third, selecting a new to-be-displayed object from the to-be-displayed moving object set with the first to-be-displayed object deleted, and placing the new to-be-displayed object into the video synopsis according to a moving trail of the new to-be-displayed object in the original video, and deleting the new to-be-displayed object in the to-be-displayed moving object set. The above operations are continued till the to-be-displayed moving object set becomes a null set, and a final to-be-displayed video synopsis sequence is obtained. Through the method, the display effects of a low moving object overlapping ratio and a low ineffective video clip ratio in a video display process are well achieved, and user experience is improved comprehensively.
