11 shows, (a) is the synthesis result from original DIBR algorithm[1].
Then the receiver side performs DIBR operation to generate the left-eye and right-eye images.
3, they have two common features: (1) the depth value is changed when the watermarking information is embedded, but the variation is limited to a small range to guarantee the virtual views have zero distortion after the DIBR process.
However, the intermediate images generated by DIBR cannot be completely restored to the original due to inadequate depth information and the occlusion problem.
However, more big holes are produced on DIBR intermediate images if the lower precision of depth map is used.
des]) are matching points in reference image and destination image respectively; n is the number of virtual view when multi views are generated using DIBR for an auto-stereoscopic display, if destination image is left view, n < 0, otherwise n > 0; r represents scale factor; Dzps is the depth of ZPS plane [12][14], and D([u.
In a DIBR system with shift-sensor camera setup, there are only horizontal parallaxes contained in the generated stereo pair (see equations in (1)).

In section 2, we provide a 3D image warping equation that implies the horizontal sensor parallax for DIBR system.
As mentioned above, if a 3D TV system adapts the depth-image-based 3D video format, then DIBR is required to be performed at the receiver side so as to create virtual views (destination images).
As discussed earlier, DIBR often involves a considerable amount of pre-processing and post-processing operations to compensate for the deficiencies of the depth maps.
Moreover, a depth map with low quantization levels was evaluated to estimate the minimum required accuracy of depth information in DIBR.
