Abstract
3D multimedia content has been more common,and the issue of content protection for 3D multimedia is more important.In previous works,they all focused on watermark how to survive in depth-Image-based-Rendering. Recently an objective 3D image quality assessment based on Binocular Perceptual
Model is purposed. We apply it on discrete cosine transform domain and divide all frequency bands into five frequency regions.In this work,we find out which frequncy regions is more fit in embedding watermark and embed different watermarking strength on different frequency regions.Finally,we can acquire better quality with our purposed method in comparison with previous works.
