Multiple elemental image mapping for resolution-enhanced orthographic view image generation based on integral imaging

In this paper, we propose an orthographic view image generation method based on integral imaging called multiple elemental image mapping. The proposed method is based on matching regions in multiple elemental images, which are generated with different micro-lens from the same area of a 3D object. By mapping all the matching regions to the corresponding orthographic view plane, we can enhance the resolution of the generated orthographic view image. Simulation experiments are carried out, and the results show the resolution of orthographic view image is improved obviously.
