title: Frequency domain depth filtering of integral imaging.
abstract: A novel technique for depth filtering of integral imaging is proposed. Integral imaging captures spatio-angular distribution of the light rays which delivers three-dimensional information of the object scene. The proposed method performs filtering operation in the frequency domain of the captured spatio-angular light ray distribution, achieving depth selective reconstruction. Grating projection further enhances the depth discrimination performance. The principle is verified experimentally.
