Abstract

The development of a compression algorithm for reduction of the transmission bit rate of 3D integral TV pictures is discussed. The proposed full parallax 3D image compression algorithm takes advantage of the cross correlation between the multiple images recorded on a CCD placed behind a directionally selective microlens array as well as the correlation inherent within each image. Tests carried out show that by using a hybrid DPCM/DCT coding scheme to code a still 3D integral TV image, a high compression performance can be obtained while retaining all the necessary information to reconstruct a faithful duplicate of the original 3D image. A coding scheme for moving integral 3D images is also described
