ABSTRACT: Recently, the popularity of 3D content is
on the rise because of its immersive experience to view- ers. While demands for
3D contents and 3D technologies increase, only a few copyright protection
methods for 3D contents have been proposed. The simplest infringement is the
illegal distribution of the single 2D image from 3D content. The leaked image
is still valuable as 2D content and the leakage can be occurred in DIBR system.
To detect the leaked image, we focus on the hole-filled region which is caused by
the hole-filling procedure mandatory in DIBR system. To estimate the
hole-filled regions, two different procedures are conducted to extract edges
and to estimate 3D warping traces, respectively. After that, the hole-filled
regions are estimated and the left-right-eye image discrimination (LR
discrimination) is also conducted. Experimental results demonstrate the
effectiveness of the proposed method using quantitative measures.
