Anti-Cross-Interference Technique Based on Integral Imaging

Mutual interference between elemental images is a key problem of integral imaging. Some researchers presented a method to resolve the problem by limiting the aperture to limit the direction of incident light-ray, and the record region corresponding to each micro-lens had been separated, avoiding interference between adjacent elemental images. However, this method must be used at the process of picking up integral image; moreover, the parameters of micro-lens array are relatively small, so adjustment is not conducive to a more accurate and easy to produce deviations. This paper presents a novel pixel compensation technique to elemental images based on computational integral imaging, finds out the correlation between elemental images, using the correlation to process the edge pixels, and eliminates cross-interference between elemental images, to a large extent, ghosting problem in reconstruction has been resolved.
