Sprite is an image constructed from video clips and is also a medium for multimedia applications. An automatic sprite generation with foreground removal and super-resolution is proposed in this paper. To remove the foreground objects, each pixel-value on the sprite is iteratively updated by the value with maximum appearance probability on temporal and spatial distribution. By storing the half-pixel, super-resolution sprite has less blurring-defect from source video. In the result, the generated sprite preserves the complete scenes of background and has higher image quality, and it can used to increase the visual quality in current sprite applications and also employed to facilitate video segmentation.
