标题： Real-Time Computational Visual Aberration Correcting Display Through High-Contrast Inverse Blurring

摘要： 本文提出了一种框架，用于开发一种实时视觉校正显示器（VCD），以解决屈光视觉异常问题，而无需传统的视力矫正设备，如眼镜或隐形眼镜，特别是在佩戴这些设备可能不方便的情况下。 我们通过使用与观看者眼睛相关的点扩散函数（PSF）对显示图像进行反卷积来实现这种校正。 我们通过在预过滤图像上应用掩码技术来解决环形伪影问题。 我们还通过在YUV/YCbCr颜色空间中操作来增强显示器的对比度并减少颜色失真，其中仅在亮度（亮度）通道上进行反卷积。 最后，我们引入了一种计算实时PSF的技术，该技术根据观看者相对于屏幕的球坐标进行适应性调整。 这确保了当观看者从相对于屏幕法线的角度观察显示器时，PSF仍保持准确且不失真，从而无论观看角度如何都能提供一致的视觉校正。 我们显示器的结果显示了视觉清晰度的显著提高，达到了结构相似性指数（SSIM）83.04%，突显了我们方法的有效性。 显示英文摘要

摘要： This paper presents a framework for developing a live vision-correcting display (VCD) to address refractive visual aberrations without the need for traditional vision correction devices like glasses or contact lenses, particularly in scenarios where wearing them may be inconvenient. We achieve this correction through deconvolution of the displayed image using a point spread function (PSF) associated with the viewer's eye. We address ringing artefacts using a masking technique applied to the prefiltered image. We also enhance the display's contrast and reduce color distortion by operating in the YUV/YCbCr color space, where deconvolution is performed solely on the luma (brightness) channel. Finally, we introduce a technique to calculate a real-time PSF that adapts based on the viewer's spherical coordinates relative to the screen. This ensures that the PSF remains accurate and undistorted even when the viewer observes the display from an angle relative to the screen normal, thereby providing consistent visual correction regardless of the viewing angle. The results of our display demonstrate significant improvements in visual clarity, achieving a structural similarity index (SSIM) of 83.04%, highlighting the effectiveness of our approach.
