Layered-depth image using pixel grouping

Recent advance in computer hardware and Internet technology makes more realistic images affordable on our computer systems. However, the image creation by using conventional geometry modelling have limitations in terms of rendering time and image quality to be used in interactive rendering applications. Image-based rendering (IBR) technique is a good solution to reducing those limitations in such applications. As an improvement on the well-known layered-depth image (LDI) method, we propose a way of pixel grouping from depth images and making image generation efficient by utilizing the information obtained from the grouping.
