二维转三维 图割 随机游走 软分割
2017/1/4
半自动2D转3D将用户标注的稀疏深度转换成稠密深度,是解决3D片源不足的主要手段之一.针对现有方法利用硬分割增强深度边缘引入误差的问题,提出像素点与超像素深度一致性约束的边缘保持插值方法.首先,建立像素点深度和超像素深度传播的能量模型,通过像素点与所属超像素间深度差异的约束项将二者关联起来;其次,利用矩阵表示形式将两个能量模型的最优化转换成一个稀疏线性方程组的求解问题.通过超像素提供的约束项,可避...
2D视频转3D视频是解决3D片源不足的主要手段,而单幅图像的深度估计是其中的关键步骤.提出基于加权SIFT流深度迁移和能量模型优化的单幅图像深度提取方法.首先利用图像的全局描述符从深度图数据库中检索出近邻图像;其次通过SIFT流建立输入图像和近邻图像之间像素级稠密对应关系;再次由SIFT流误差计算迁移权重,将近邻图像对应像素点的深度乘以权重后迁移到输入图像上;然后利用均值滤波对迁移后的近邻图像深度...
