3D 數位多媒體內容(如3D 立體電影) 在現今生活中已變得相當普
及,保護其智慧財產權當然成為重要的議題。在目前的3D 智財權相關
文獻裡,主要都是在討論浮水印如何在深度圖生成技術上能強健地被
保留下來,卻甚少有文獻討論浮水印與3D 立體影像品質的關係。本
論文根據由雙眼視覺模型系統提出的3D 立體影像品質評量,將其系
統轉換至離散餘弦轉換上,使離散餘弦頻率域分別對應至五個立體影
像品質評量最主要的頻帶上,找出可嵌入浮水印的頻域後,並對可嵌
入浮水印的不同頻帶加上不同強度的浮水印,使3D 數位內容在擁有
強健的浮水印後還能擁有不錯的3D 影像品質。

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.
