In our previous studies, we studied on the multi-view 3D CG image quality evaluation including visible digital watermarking. Particularly, we verified for the multimedia evaluation including both the coded image quality and watermark quality. Actually, the image quality of watermarking is not always better in case we carried out the visible digital watermarking. Therefore, depending on the situation, we need to change the coded image quality of watermarking. In this paper, we used 3D CG images with 8 viewpoints parallax barrier method, which embedded the watermarking image encoded and decoded by H.265/HEVC in advance by transforming frequency domain for the generated images. And then, we composed the generated images. We carried out the subjective quality evaluation of these images, and then we analyzed results, and classified evaluation values by using Support Vector Machine (SVM). Furthermore, we considered for the application procedure of watermarking by comparing mutually to the case of considering the coded image quality of watermarking.
