摘要
基于深度图的视点渲染(DIBR)是支撑3D视频服务的一种重要技术。为了解决任意视点绘制结果中常出现的虚假边缘问题,本文在前向映射过程中采用了一种深度图不连续区域检测的算法,且在后向映射过程为了节省计算成本仅对必要的像素点集处理,并对alpha融合后的图像进行纹理修复,获得了高质量的视点绘制结果。实验证明,在微软提供的多视点数据集上测试得到PSNR和SSIM指标都优于DIBR标准参考方法的处理结果。
Depth Image Based Rendering（DIBR） technique has been recognized as the most important technique to provide 3d video services. In order to remove the ghost contours in the final rendered view, this paper proposed a depth-based discontinuous region detection algorithm in the forward warping process, and then process the changed pixels in the inverse warping, finally inpaint the alpha blended view to obtain high-quality virtual view. Experiments show that the results of PSNR and SSIM metrics outperform that of the standard reference method on the multi-view dataset provided by Microsoft Research.
