Integral imaging is a kind of true three-dimensional (3D) display technology that uses lens array to reconstruct vivid 3D images with full parallax and color. In order present high-quality image, it’s vital correct the axial position error caused by misalignment deformation which makes reconstructed lights deviate from directions, resulting in severe voxel drifting image blurring. We proposed sub-pixel marking method measure lenses great accuracy addressing sub-pixels under each forming...
Compared with conventional scattered backlight systems, integral imaging (InIm) display system collimated can reduce the voxel size, but apparent separation and severe graininess still exist in reconstructed 3D images. In this paper, an InIm anisotropic control of sub-pixels was proposed to resolve both aliasing simultaneously. It consists unit (ABU), a transmissive liquid crystal panel (LCP), lens array. The ABU specific horizontal vertical divergence angles designed. Within depth field,...
In traditional computer-generated integral imaging (CGII) methods, the generated elemental image array (EIA) is flat, and it doesn't fit for curved (II) systems. Here, a CGII method was proposed II system. method, multiple virtual camera arrays (VCAs) were built up to determine origins directions of traced rays. Combined with backward ray-tracing (BRT) technique, EIA generated, rendering time same as BRT-CGII flat A system consisting organic light emitting diode display screen, lens optical...
Potent usage of the multi-scale light field information for salient object detection (SOD) is essential requirement three-dimensional (3D) SOD. On this basis, a 3D-SOD scheme proposed that employs pixel mapping algorithm to achieve more distinct representation spatial and angular in four-dimensional (4D) field, collaboratively mining global saliency cues via co-salient (CoSOD) network. Compared with previous method, our filters out most noise by thoroughly leveraging dependence 4D offering...
