Image acquisition for free-view displaying and its subjective-objective image evaluations

Recently, 3D and free-view displaying technologies are getting attention in movie and electrical industries. However, these technologies require to obtain a large amount of images with different viewpoints. The images are too redundant, since the images are almost similar to the neighboring viewpoints, although the expensive equipment such as large camera array and huge storage are required to capture and store the images. In this paper, we propose to capture smaller number of viewpoints and lower resolution of images, then we interpolate the viewpoints or resolution by image processing technique for the effective acquisition of multiple view images. We evaluated the image quality in objective and subjective experiments and discuss about the trade-off between the quality and effectivity.
