Automultiscopic (no glasses, multiview) displays are becoming a viable alternative to 3-D displays with glasses.
However, since these displays require multiple views the needed transmission bit rate as well as storage space
are of concern. In this paper, we describe results of our research on the compression of still multiview images
for display on lenticular or parallax-barrier screens. In one approach, we examine compression of multiplexed
images that, unfortunately, have relatively low spatial correlation and thus are difficult to compress. We also
study compression/decompression of individual views followed by multiplexing at the receiver. However, instead
of using full-resolution views, we apply compression to band-limited and downsampled views in the so-called "N-tile
format". Using lower resolution images is acceptable since multiplexing at the receiver involves downsampling
from full view resolution anyway. We use three standard compression techniques: JPEG, JPEG-2000 and H.264.
While both JPEG standards work with still images and can be applied directly to an N-tile image, H.264, a video
compression standard, requires N images of the N-tile format to be treated as a short video sequence. We present
numerous experimental results indicating that the H.264 approach achieves significantly better performance than
the other three approaches studied.
