It can be used for efficient video coding, video summary, browsing, and editing. In this paper, three new techniques for sprite generation are proposed. Boundary matching and multiple sprites techniques can improve the subjective quality with refining the positions of the warped frames and generating more than one sprites. The frame skipping technique can skip redundant frames that contain only little new information when the camera revisits a scene several times to accelerate the sprite generation process. Experimental results show that these techniques can be employed independently and can improve the subjective quality as well as reduce the 47.68% - 17.22% runtime of sprite generation. They can be applied with any sprite generation algorithms. © 2002 IEEE. |
