General Hogel-Based Effective Perspective Image Segmentation and Mosaicking Method for Holographic Stereogram Printing
The hogel-based effective perspective image segmentation and mosaicking (EPISM) method utilizes a two-step approach for holographic stereogram printing. This method can generate a holographic stereogram with high-quality reconstructed images using only a few sampled images. However, this method needs to establish an accurate correspondence among hogels to obtain effective perspective image segments, and it can be utilized only when certain position constraints are satisfied. To solve this problem, we propose a general hogel-based EPISM method for holographic stereogram printing in this study. The proposed method uses an approximate correspondence of hogels instead of an accurate correspondence of hogels to obtain several effective perspective image segments, so it can be applied to general cases. Furthermore, using optical experiments, we verify that the proposed method can generate a holographic stereogram with high-quality reconstructed images by employing a few sampled images. Although the way to obtain the effective perspective image segments is different, the reconstructed images of the holographic stereograms obtained by the two methods are with the same good quality. The printing efficiency of the proposed method is higher than that of the EPISM method, and the proposed method can also be utilized to improve the “pixel correspondence” holographic stereogram.
