3D displays are capable of immersive 3D content presentation without glasses and
headsets. The displays project different views depending on the user's viewing
angle. Multiple views are visible to the user at once to simulate the 3D
perception. The visual blending of the simultaneously projected views creates
out-of-focus areas in the scene. The scene can be displayed with only one
focusing distance, where the objects appear sharp. This paper utilizes this
effect in data compression. First, several metrics are proposed for automatic
visual quality assessment of the results on the 3D display. Then, automatic
detection of the focusing distance in the scene, based on the input views, is
proposed. Based on this detection, the high spatial frequencies in out-of-focus
areas can be eliminated using the depth-of-field effect, or such areas can be
compressed with higher compression ratio, depending on the use case. The paper
compares the proposals. A user study is conducted to obtain human evaluation of
the results. The results obtained identified the optimal visual quality metric
for the 3D display. The proposed compression proved to be beneficial for 3D
displays and capable of reaching a higher compression ratio than standard methods
without a perceivable quality loss.
