A Novel Optimization Method for Lenticular 3-D Display Based on Light Field Decomposion

Crosstalk is a primary defect in affecting the image quality of stereoscopic three-dimensional (3-D) displays. Until now, the crosstalk reduction methods either require extra devices or need tedious calibration procedures, which require precise measurement on each display device. We propose herein a new method of synthesizing lenticular 3-D display based on the light field decomposition and optimization to minimize the crosstalk. The light field concept is introduced into lenticular 3-D display. Rays of multiview light field are back-projected to the LCD plane to form a synthetic image, with subpixel resolution. A weighted value considering all arriving rays is assigned for the subpixel to reduce crosstalk. We developed a new algorithm of ray's mergence and assignment for a smooth fusion of different views and crosstalk reduction. We also performed validation experiments which convincingly demonstrated that our new method is capable of reducing the crosstalk on synthetic graph. Compared with existing methods, our proposed new method is simple and effective, and implementation cost is low.
