Paper Abstract

At De Montfort University the imaging technologies group have developed an integral imaging system capable of real time capture and replay. The system has many advantages compared with other 3D capture and display techniques, however one issue that has not been adequately addressed is the measurement of the fidelity of replayed 3D images where some distortion has occurred. This paper presents a method for producing a viewing angle-dependent PSNR metric based on extraction of optical model data as conventional images. The technique produces image quality measurements which are more relevant to the volume spatial content of an integral image than a conventional fidelity metric applied to the raw, optically encoded spatial distribution. Comparisons of the previous, single metric with the new angle-dependent metric are made when used in assessing the performance of a 3D-DCT based compression scheme, and the utility of the extra information provided by the angle dependent PSNR is considered.
