摘要Depth image-based rendering (DIBR) technology is an approach to creating a virtual
3D image from one single 2D image. A desired view can be synthesised at the receiver side using
depth images to make transmission and storage efficient. While this technique has many
advantages, one of the key challenges is how to fill the holes caused by disocclusion regions and
wrong depth values in the warped left/right images. A common means to alleviate the sizes and
the number of holes is to smooth the depth image. But smoothing results in geometric distortions
and degrades the depth image quality. This study proposes a hole-filling method based on the
oriented texture direction. Parallax correction is first implemented to mitigate the wrong depth
values. Texture directional information is then probed in the background pixels where holes take
place after warping. Next, in the warped image, holes are filled according to their directions.
Experimental results showed that this algorithm preserves the depth information and greatly
reduces the amount of geometric distortion.
