Abstract
We propose a method based on the selective pixel sampling algorithm to generate a nonunified integral imaging (II) elemental image array (EIA) with reduced moiré patterns at a low rendering cost and high three-dimensional (3D) resolution. In the proposed method, the redundant 3D information is captured for the nonunified pixel arrangement of elemental images, and the moiré patterns are constrained by the constraint equations. The nonunified EIA's corresponding information is mapped from the obtained 3D information based on the selective pixel sampling algorithm. Appropriate experiments are carried out, and the experimental results show that the proposed method can increase the 3D display quality of the reconstructed 3D images in the II display and reduce rendering costs markedly in the generation of ultra-high-definition EIA.
