Depth map estimation forms an integral part of many applications such as 2D-to-3D creation. There exists various methods in literature for depth map estimation using different cues and structure. Usually, depth information is decoded from these cues at the edges and matting is applied to spread it over neighboring regions. Defocus is one such cue due to its natural existence and does not require any precondition compared to other cues. However, there can exist regions in images with no edges. These regions are referred to hole regions and are the main source of error in estimated depth map. In this paper, we propose a method to correct some of these errors to obtain an accurate depth map. The proposed method uses color uniformity principle to detect hole regions present in depth map. We also provide a framework to identify falsely detected holes in order to increase effectiveness of our method. © 2017 IEEE.
