Cropped image size && mask image size

[liushawn618]

Dear team, thanks for your great work! When I visualize mask images, I find that the mask image size is 1600 * 900, but the cropped image size is 1000 * 1000, so the mask images can't match the cropped images pixel by pixel. How can they be exactly matched? I'd be really appreciated if you could give me some advice.
