摘　　要：单路编码是目前3D信号广播使用的主要方式,为了更好地恢复亚奎斯特图像以减少失真,选择好的内插模板是关键.本文通过对单路编码的四种方式进行了频谱分析,提出使用一种新的二维Fourier加窗内插模板.在对图像边界拓展方面。指出使用偶拓展可以更好地降低失真,并通过实验验证,使用15×15无窗、单窗和双窗三种模板对三种亚取样3D图像进行恢复处理的效果明显优于传统处理方法,并获得8dB的增益,提高了3D恢复他图像的主客观质量.Single link coding is the major method used in current 3D signal communication,in which choosing a good interpolating template is the key point to better recover the sub-sampled image with low distortion.In this paper,by analyzing the spectrum of four single link coding method,a novel 2-dimention Fourier interpolating with window is presented.Four the boundary expanding of image,it is pointed that even-expanding is better in lowing distortion.Finally simulation testing is designed and verifies that the images recovered by three types of windowed-templates from sub-sampled 3D image have higher SNR by 8 dB and better subjective and objective 3D quality than that recovered in no overlapping way.
