Research Abstract

In order to realize useful visual media such as 3-D images, we need effective technology for representing and utilizing dense light fields, that is to say, information of rays flying in the space. At first, this research formulates essential relation between some images structured appropriately and the light filed in the frequency domain. Then, a novel method for such image acquisition is proposed. Finally, based on the relation above, fast and robust reconstruction of a dense light field from the acquired images is achieved.
