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.
