Occlusion-aware depth estimation for light field using multi-orientation EPIs

作者:

Highlights:

• We introduced a method to extract various directions of EPIs and showed that the optimal EPI has the same direction as the occlusion boundary.

• We proposed to detect the occlusion boundaries based on the variance and gradient of local depth values, and find the accurate depth label from the optimal EPI.

• We developed a novel framework that combines the local disparity map with the occlusion boundary to deal with occlusions so as to obtain robust depth maps.
