Abstract
A system and method are provided for analyzing 3D digital content to determine whether a watermark is detectable. The watermark may exist in 2D content that is converted to 3D, and in such cases, the survivability of the watermark to the conversion process is evaluated. An anticipated location of the watermark in left and right 3D images may be determined, and the detectability based upon the anticipated location. A report may indicate whether the watermark survived the conversion in one or both images, or neither. The process may be performed for single frames, sequences of single frames, or entire files containing many image frames. Watermark placement may also be proposed for locations in 2D content, 3D content, or both. Watermarks may similarly be placed in the content.
