摘要： 针对现有的图像融合算法存在频域混叠现象及通用性差的问题，提出一种基于柱镜光栅的自由立体图像融合算法。在低通抗混叠滤波前对视点图像进行非等比例上采样，调整视点图像亚像素映射公式，强化公式的通用性。实验结果表明，该算法在定性的视觉效果及定量的图像质量评估方面都具有一定的优势。

Abstract: Existing image fusion algorithms have the phenomenon of frequency-domain aliasing, and the commonality of algorithms is poor. Aiming at this problem, this paper improves an algorithm from the aspects of low-pass anti-aliasing filtering and sub-pixel mapping point of view, and makes the sub-pixel mapping formula more general. Experimental results show that the improved algorithm has certain advantages in qualitative visual effects and quantitative image quality assessment.
