Abstract
A depth-fused 3-D (DFD) display, which is composed of two 2-D images displayed at different depths, is a new 3-D display proposed recently and enables an observer using no extra equipment to perceive an apparent 3-D image. The original data for it are a 2-D image of objects and a depth map image of objects. The two 2-D images are formed by dividing the luminance of an original 2-D image between the two 2-D images according to a depth data of objects at each pixel. This paper presents the effect of the compression of the depth map image on a DFD image. We studied on still pictures using JPEG as an algorithm for compression. After decoding the depth map image, 3-D images were displayed forming the two 2-D images. The main result obtained from subjective evaluations is that the effect of the compression noises appearing on its decoded image appears as errors of position in depth on DFD image, however, a higher compression rate is possible for depth map image than for conventional 2-D image. This result shows that is is advantageous to transmit or store the original data before forming the two 2-D images.
