一种用于DIBR的去隔行算法

摘要

提出了一种适用于DIBR的去隔行算法.该算法首先采用一种基于方向的场内插值算法对隔行参考图像及其深度图像去隔行,这种场内插值算法能够通过对插值方向进行自适应的选择,有效地消除锯齿现象;然后算法会根据逐行的参考图像及其深度图像进行三维图像变换,得到逐行的目标图像.实验表明,所提出的去隔行算法能得到画质较高的逐行新视图,且算法性能是鲁棒的.该算法适用于基于DIBR的3D视频的去隔行.%The de-interlacing algorithm for DIBR first performed de-interlacing on an interlaced reference image and its depth image by an intra-field interpolation algorithm based on direction.The interpolation algorithm worked well in eliminating jagged effect by adaptively selecting the direction of interpolation.Then, applied 3D image warping to the progressive reference image and its depth image to generate a progressive destination image.Experiment results show that the proposed de-interlacing algorithm can provide progressive novel views with quite good image quality, and the performance is robust.The algorithm adapts to the de-interlacing of DIBR-based 3D video.
