How do you normalize depth value to fall into 0-255? #21

I have appreciated your great work. You noted that depth value in NYUDv2 datasets should be normalized. I found that the maximum pixel value of raw depth image is very large(ie, 19576 of 000003.png in dataset) and it has much 0 value. Is it normal? How should I do to normalize it? Look forward to your reply. Thanks!

Yes it is normal to have missing depth, encoded with 0. You can divide the numbers by 1000. to convert them to meter.
