摘要

本文提出了一种基于改进动态规划的光线空间插值方法

区别于传统的动态规划算法

本文先利用扫描线间的平滑约束来消除条纹效应

并采用增量计算方案来加速动态规划算法中最耗时的匹配代价计算.然后

采用以视点为中心的视差估计方法插值出稠密的光线空间数据.最后

从光线空间数据快速生成高质量的任意视点图像.该方案采用Middlebury和3DTV数据库作为测试数据

实验结果表明

新方法在计算效率和生成视点图像的PSNR上优于块匹配插值方法和视差域滤波方法.

Abstract

This paper presents an improved dynamic programming(DP)based ray-space interpolation for arbitrary view rendering.Different from the conventional DP method

a smoothing constraint of inter-scanlines is applied to eliminate the "streaking" artifact

and the most time-consuming step of computing matching cost is carried out by an incremental computation scheme.Then

dense ray-space data are interpolated by a view-centered disparity estimation method.Finally

arbitrary viewpoint image with high quality can be rendered from this dense ray-space easily.The proposed scheme is evaluated on the Middlebury data set and 3DTV test data.The experimental results show that the PSNR and computational efficiency of the proposed rendering method are much higher than that of the other two schemes.
