基于邻域扩展的半自动2D 转3D 方法
Semi-automatic 2D-to-3D conversion based on neighbors extension
摘要
Abstract
Semi-automatic 2D-to-3D conversion is a promising solution to 3D video creation.Existing methods obtain dense depth-map based on similarities in local neighbors which neglects the global constraints in image.Therefore,these methods can-not recover the object boundaries of depth-map accurately.To help solve this problem,this paper proposed a depth interpolation method using optimization based on neighbors extension.Firstly,it developed an energy model for depth interpolation by consi-dering distant neighbors.Secondly,it obtained a closed form solution of this model by assuming that similar pixels had similar depth differences between their weighted average value in local neighbors.Experimental comparisons with the popular tech-niques show that the proposed method demonstrates advantages over PSNR and depth object boundaries.关键词
