Title:
EFFICIENT SUB-PIXEL DISPARITY ESTIMATION FOR ALL SUB-APERTURE IMAGES FROM DENSELY SAMPLED LIGHT FIELD CAMERAS
Document Type and Number:
WIPO Patent Application WO/2018/112875
Kind Code:
A1
Abstract:
A system for sub-pixel disparity estimation is described herein. The system includes a plenoptic camera, a memory, and a processor. The memory is configured to store imaging data. The processor is \coupled to the memory and the plenoptic camera. The processor is to obtain a plurality of sub-aperture views, select a subset of sub-aperture views as reference views for a disparity calculation, and calculate an integer disparity for the reference views. The processor is also to refine the integer disparity to sub-pixel disparity accuracy for the reference views and propagate the sub-pixel disparity from the reference views to other views of the plurality of sub-aperture views.
