摘要： Automultiscopic displays enable glasses-free 3D viewing by providing both binocular and motion parallax. Within the display field of view, different images are observed depending on the viewing direction. When moving outside the field of view, the observed images may repeat. Light fields produced by lenticular and parallax-barrier automultiscopic displays may have repetitive structure with significant discontinuities between the fields of view. This repetitive structure induces visual artifacts in the form of view discontinuities, depth reversals, and extensive disparities. To overcome this problem, a method modifies the presented light field image content and makes it more repetitive. In the method, a light field is refined using global and local shearing and then the repeating fragments are stitched. The method reduces the discontinuities in the displayed light field and leads to visual quality improvements. Benefits of the method are shown using an automultiscopic display with a parallax barrier and lenticular prints.

摘要翻译：自动显示显示器通过提供双目和运动视差来实现无眼镜3D观看。在显示视野内，根据观察方向观察不同的图像。当移动到视野外时，观察到的图像可能会重复。由透镜和视差屏障自动显微镜显示器产生的光场可能具有在视场之间具有显着不连续性的重复结构。这种重复结构以视图不连续性，深度反转和广泛的差异的形式引起视觉伪影。为了克服这个问题，一种方法修改了所呈现的光场图像内容并使其更重复。在该方法中，使用全局和局部剪切来改进光场，然后缝合重复的片段。该方法减少显示的光场中的不连续性，并导致视觉质量的改善。使用具有视差屏障和透镜状印刷的自动显微镜显示该方法的优点。
