Photometric consistency loss

WebFirst, a patch-wise photometric consistency loss is used to infer a robust depth map of the reference image. Then the robust cross-view geometric consistency is utilized to further decrease the matching ambiguity. Moreover, the high-level feature alignment is leveraged to alleviate the uncertainty of the matching correspondences.
