Sprite pyramid for videos and images having finite-depth scenes

The ordinary sprite generation techniques focus on camera movement, accurate motion estimation, alignment, and integration. These techniques ignore the resolution of original images and the regenerated images from the sprite are likely to have lower resolutions than the original ones. Especially, if the scenes have finite depth and zoom-in and zoom-out operations occur, the segments of the scene are captured at different resolutions. The traditional mosaic generation methods either blur the mosaic by integrating lower resolution segments or use unnecessary large storage for the mosaic. The sprite pyramid (or layered sprite) allows efficient storage of images or video clips of overlapping scenes at different resolutions. Moreover, the images or video frames can be reconstructed from the sprite pyramid at the necessary resolutions.
