Method and Apparatus for Robust Depth Image Estimation of Light Fields

摘要

A robust light field depth image estimation method and apparatus are presented. The robust light field depth image estimation method proposed in the present invention measures the data cost by using the attributes of the light field image including each patch and the refocus image in order to estimate the data cost for the depth label candidates of the pixels of each patch Measuring the consistency of pixel colors of each patch by calculating each constrained entropy cost to calculate a data cost in a corresponding relationship between pixels of each patch; obtaining a pixel of each patch that is consistent with the occlusion phenomenon; The cost of data measured using the attributes of the light field image, the cost of the data for measuring the fitness for the depth label candidate, and the data cost for maintaining flatness between adjacent pixels. To normalize each constrained entropy cost and constrained adaptive non-focus (CAD) cost Sum and by including the step of forming a final cost data.
