Abstract :
We propose a mixed-resolution coding architecture for stereo color-plus-depth images, where encoding is performed at a low resolution, except for one of the color images. Super-resolution methods are proposed for the depth maps and for the low-resolution color image at the decoder side. Experiments are carried out for several real and synthetic images and reveal a reduction in complexity at the encoder associated with average PSNR gains of the super-resolved low-resolution color image with respect to regular interpolation.
