Abstract

Light field display technology can achieve glasses-free 3D visualization by simulating the direction of light rays. However, the balance between angular resolution and spatial resolution restricts the fidelity of depth perception. Previous light field display technologies uniformly distribute the rendering density over the entire light field volume, ignoring the fact that the depth complexity of scenes varies over spatial regions. This paper presents a rendering density adaptive light field display system with the addition of depth gradient analysis and the development of a perceptual depth salience model incorporating a binocular sensitivity function and a texture masking factor based on the characteristics of the human visual system. The system employs a three-tier quantization strategy with adaptive Otsu thresholding and a boundary blending mechanism to ensure seamless transitions between density tiers. Experimental results confirm the proposed system can achieve improved depth perception MOS by 15.1 percent and reduce rendering computation by 38.2 percent with similar accuracy as the uniform density rendering.
