图像分辨率问题

[QingWindIsStillTheWind]

I would like to ask the next author, if the size of the image used for network training is 960x540, then when I want to use this network test, the resolution of the photos taken by my camera is very large, such as 4608x3456. When I take this picture to train, the parallax map effect is very bad. When I reduce the original image to 960x540, the parallax map effect is very good OK, but I don't know how to restore the parallax value of the original image. Hope that the author can guide, thank you very much!
