Elemental image array generation based on discrete viewpoint pickup and window interception in integral imaging.

We present a method to generate the elemental image array (EIA) in integral imaging in this paper. The discrete viewpoint image array is captured from a discrete viewpoint pickup platform and is treated by a window interception algorithm to obtain the subimage array (SIA). The EIA can be obtained from the SIA according to the transformation relationship between the EIA and SIA. We employ the EIA to display in the integral imaging system, indicating that the proposed method can truly represent the structure of the objects.
