Rendering with concentric mosaics

摘要

This paper presents a novel 3D plenoptic function,which we call concentric mosaics.We constrain camera motion to planar concentric circles,and create ocncentric mosaics using a manifold mosaic for each circle (i.e.,composing slit images taken at different locations).Concentric mosaics index all input image rays naturally in 3 parameters: radius,rotation angle and vertical elevation.Novel views are rendered by combining hte appropriate captured rays in an efficient manner at rendering time.Although vvertical distortions exist in the rendered images,they cna be alleviated by depth correction. Like panoramas,ocnentric mosaics do not requre recovering geometirc and photometric scene models.
