A Fast and Efficient Video Shot Mosaicing Approach Based on Motion Characteristics

Presenting more comprehensive visual information than key-frame,mosaic has been an important element for many vision tasks.This paper proposed a fast and efficient video mosaicing approach based on motion characteristics,which investigated two important issues affecting the quality of mosaic.First,given a video shot,a motion entropy based method is to determine whether the visual content of a shot is suited to be represented by a mosaic.Second,if so,a suitable subset of frames in this shot is selected for efficient and effective mosaicing by constructing a global motion path.Experiments compared to traditional mosaicing have proved that with this approach,not only the visual quality of mosaic is significantly improved,but also the computational time is remarkably reduced.
