A method to adaptively code multiview videos has been proposed which uses the depth characteristics of automultiscopic displays. It is found that for the 3D scene seen on automultiscopic displays, regions appearing at large depths are rendered blurry. The proposed method identifies such regions and uses fewer bits to code them. Also, greater number of bits are used for regions which appear sharp on the 3D displays. The overall quality is better than regular AVC/H.264. For compatibility with the framework of scalable multiview coding, we introduce depth scalability. This ensures that the (hierarchical layerwise) encoded video bitstream can be optimally displayed on various displays with different depth properties.
