【摘要】 提出了基于片间相关性的光线空间插值算法,利用邻近参考片已知视差,快速预测当前片视差,使得当前片视差估计的搜索限制在预测视差附近的小范围内进行,从而大大降低了计算复杂度.根据视差参考方式的不同,设计了三种实现方案.实验结果表明,采用双向视差参考方案插值生成的光线空间片不但信噪比高、绘制视点图像主客观质量较高,而且插值与绘制速度也有了明显提高.更多还原

【Abstract】 Based on the analysis of inter-slice correlation in ray space,a new ray space interpolation method was proposed.Using the disparities of neighboring slices,the searching range of disparity estimation was restricted arround the predicted disparity so that the computational complexity of disparity estimation was reduced.Three schemes were proposed according to different reference of dispatiry during ray space data interpolation.The experimental results show that the scheme of bidirectional reference of parallax can obviously improve the speed of ray space interpolation and achieve higher PSNR and well subjective image quality.更多还原
