Abstract
The present invention provides a method and an apparatus for processing a light-field image. The method includes: acquiring a light-field image; acquiring an occlusion tag function of each unit image in the light-field image; determining a cost function for offset estimation of each unit image according to intensity change information and gradient change information that are of each unit image in the light-field image and the occlusion tag function of each unit image; acquiring an offset of each unit image in the light-field image by using the cost function; and reconstructing a high-resolution light field by using the offset of each unit image. An offset of each unit image in a light-field image may first be acquired according to optical flow change information of the light-field image, and then a high-resolution light field is reconstructed by using the offset of each unit image, so as to effectively improve spatial resolution.
