Salience Guided Depth Calibration for Perceptually Optimized Compressive
Light Field 3D Display
Abstract
Multi-layer light field displays are a type of computational three-dimensional (3D) display which has recently
gained increasing interest for its holographic-like effect
and natural compatibility with 2D displays. However, the
major shortcoming, depth limitation, still cannot be overcome in the traditional light field modeling and reconstruction based on multi-layer liquid crystal displays (LCDs).
Considering this disadvantage, our paper incorporates a
salience guided depth optimization over a limited display
range to calibrate the displayed depth and present the maximum area of salience region for multi-layer light field display. Different from previously reported cascaded light field
displays that use the fixed initialization plane as the depth
center of display content, our method automatically calibrates the depth initialization based on the salience results
derived from the proposed contrast enhanced salience detection method. Experiments demonstrate that the proposed
method provides a promising advantage in visual perception for the compressive light field displays from both software simulation and prototype demonstration
