Abstract (in Japanese) (See Japanese page) 
(in English) It is important for assessors to focus on what region of an image, and we need to evaluate including the multi-physical factor. Previously, we studied about multi-view 3D image quality evaluation by focusing on the coded image quality by regions, however, we did not consider the visible digital watermarking by regions. It is not clear that the evaluation in the case of processing the coded image quality and the visible digital watermarking by regions and their mutual relations including the image contents. Therefore, we need to verify the relation between the coded image quality and the content including visible digital watermarking by regions. In this paper, first, we generated the watermarking image by region for contents by processing of the clipping mask for 3D CG images by regions and the watermarking image. Next, we processed watermarking by regions of the multi-view 3D CG image encoded and decoded by H.265/HEVC by frequency domain transformation. We obtained the generated images by composing viewpoints. And then, we carried out the evaluation experiment of the generated image with 8 viewpoints parallax barrier method. From results, we analyzed and classified the evaluation values statistically for the image region and the coded image quality by Support Vector Machine (SVM).
