Enhancing Stereo Image Quality based on Adaptive Hole-Filling of Depth Image for Kinect Camera

摘要

Kinect camera produces depth images as well as color images. Yet undefined depth regions called holes are often observed in the depth image and are quite harmful in generating a second view image to construct a stereo pair for 3D viewing. An adaptive hole-filling method that can fill in even very large holes more naturally is proposed so that depth values for holes of various sizes are suitably estimated depending on the location of holes in the background or foreground. Removal of dot noise inside a hole is also introduced to further enhance the quality of the newly generated stereo image.
