Sprite generation is the process of aligning, warping, and blending of pixels that belong to an object in a video. The evaluation of the correctness of a sprite is usually accomplished by a combination of objective and subjective evaluations. Availability of ground-truth image would help mere objective evaluation. In this paper, the authors present video generation from an image based on various camera motion parameters to be used as ground-truth for the sprite evaluation. This paper introduces a framework for evaluation of sprite generation algorithms. Experiments under the proposed framework were performed on the synthetic videos of different camera motion patterns to reveal the components of the sprite generation algorithm to be improved.

Sprite coding, accepted by the emerging MPEG-4 standard is a very efficient method for representing the background video object. Still this sprite generation is an open issue due to the foreground objects which obstructs the accuracy of camera motion estimation and blurs the generated sprite. In this paper we propose a method for constructing the background sprite with partial decoding of the MPEG stream. Initially the Independently Moving Objects (IMO) are segmented out from the background by clustering the pre-processed motion vectors of MPEG video. The camera motion parameters are obtained from the motion information corresponding to the background region which is used for frame alignment.
