Enhanced compression rate of integral images by using motion-compensated residual images in three-dimensional integral-imaging.

In this paper, we proposed a new approach to notably enhance the compression rate of integral images by using the motion-compensated residual images (MCRIs). In the proposed method, sub-images (SIs) transformed from the picked-up elemental images of a three-dimensional (3-D) object, are sequentially rearranged with a spiral scanning topology. The moving vectors among the SIs, then, are estimated and compensated with the block-matching algorithm.
