Abstract

We propose an interpolation method to effectively improve the visual quality of the reconstructed integral image. Specifically, the dot-pattern output plane image (OPI) is first generated based on the pickup EIs by using pixel-to-pixel mapping. Then all the zero pixels in the dot-pattern OPI are interpolated by utilizing a non-zero-pixel derivation technique, and the final reconstructed integral image is obtained. To confirm the feasibility of this method, some computational experiments were carried out for test plane images with different depths. Quantitative experimental analysis shows that our proposed method has good robustness and can largely enhance the viewing quality of the reconstructed integral image compared to the plane-by-plane reconstruction technique and the conventional pixel-to-pixel mapping and interpolation technique.
