Compression with mosaic prediction for image-based rendering applications

In this paper, we present a mosaic based compression scheme for image-based rendering applications in which a sequence of images is captured by a camera located at different positions along a circle. The mosaic image is constructed first and then using a general video codec. Section 4 describes the mosaic based compression scheme. Our experiments are described and the results are analyzed in Section 5. Finally, we provide a conclusion and outline future work in Section 6. 2. IMAGE ACQUISITION used to predictively encode the original images. Furthermore, To capture images of a real scene, an off-centered camera is motion compensation is applied to provide a closer match at the rotated along a circle [1] and the images are acquired when the block level between the prediction image and the original image. camera is at different positions. Often the camera is facing We examine this compression scheme and compare its outward with setup 1 as shown in Figure 1 (a). Once these performance with intra and inter coding using a general video images are acquired, an image viewed by a virtual camera can be codec. Our experimental result shows that mosaic based synthesized by taking pixels of the corresponding images that are compression with motion compensation provides a better already acquired as shown in Figure 1 (a). We propose to place performance in the rate-distortion sense compared with intra the camera in setup 2 as shown in Figure 1 (b). This is because coding while at the same time it has the advantage of random with setup 2 a larger field of view of the scene can be obtained access over inter coding. and there will not be any missing pixels when a virtual view is 1
