In the recently five years, image-based rendering (IBR) has been an active research area and considered as a potential approach for photorealistic rendering of complex scenes that are difficult to model and render using the traditional polygon-based graphics pipeline. The basic idea of IBR is to combine images of the scene collected from different but fixed viewpoints to create new views. Early work in image-based rendering was based on the assumptions that a large number of cameras are densely placed around the scene or the geometry of the scene is known in advance.
