Digital blind watermarking based on depth variation prediction map and DWT for DIBR free-viewpoint image
作者：
Highlights：
• A digital watermarking scheme to protect the ownership of a free-view 2D or 3D image.
• A special map, termed the depth variation prediction map (DVPM) to find locations that are safe from viewpoint change.
• The watermark embedding regions in conjunction with the DVPM.
• The watermark embedding scheme by a quantization index modulation (QIM) method.
• The blind multiple watermark data extraction.
