Method and Apparatus for Depth Image Estimation of Light Fields

摘要

A light field depth image estimation method and apparatus are presented. The light field depth image estimation method proposed in the present invention includes a step of measuring a data cost using attributes of a light field image including each patch and a refocus image for estimating a data cost for a depth label candidate of a pixel of each patch Measuring the consistency of pixel colors of each patch by calculating each entropy cost to calculate the data cost in the corresponding relationship between pixels of each patch; Measuring the unfocused cost, measuring the data cost using the properties of the light field image, the data cost measuring the fitness for the depth label candidate, and the data cost for maintaining flatness between adjacent pixels, And adaptive unfocused costs to form the final data cost. And a step.
