- Abstract
- This paper proposes a simple and efficient method to combine planar prior obtained from a triangular model with the depthvalues computed by PatchMatch. Through this approach, the accuracy of depth estimation was improved in low-textured areaswhere existing PatchMatch-based methods showed low depth estimation accuracy, and in detailed areas where the triangular modelshowed limitations in surface modeling. In the proposed method, first, initial depth and normal maps are obtained via an existingPatchMatch approach. Subsequently, a triangular model is generated from the selected node, and initial planar priors are derivedfrom this model. After refining the initial planar priors via a bilateral technique, the initial depth and normal maps are combinedwith the refined planar priors by applying a simple and efficient combining process. Experimental results show that the proposedmethod achieves superior results compared to existing approaches.
