This paper introduces an anti‐aliasing image reconstruction method in the optical coordinate domain for point‐to‐point transmission in AR/VR headset displays, employing variable downsampling ratios across different image areas to reduce transmission bandwidth and corresponding upscaling ratios at the receiver. Filter parameters for anti‐aliasing calculations at each pixel position are determined based on optical coordinates distorted by the lens, enhancing detail in areas with significant image deformation. Image quality is evaluated using MSSSIM and supported by experimental evidence.
