Question about the depth map #5

Open taylover-pei opened 4 years ago

taylover-pei commented 4 years ago

Nice. You have done a great job. But I have a question about the depth map.

In the original paper, the values of depth map are normalized to [0:1]. But, in your code, when I printed the values of the generated depth map, I find the values are just like this: image

How should I do?

Thank you very much. Looking forward to your reply.

clks-wzz commented 4 years ago

You can normalize the depth map by dividing it with 255.0.

@clks-wzz @roger-cv @taylover-pei @clks-wzz Thanks for sharing your code,

ValueError: The passed save_path is not a valid checkpoint: E:\yzu\lab\face anti spoofing\PRNet-Depth-Generation-master\Data\net-data\256_256_resfcn256_weight

but I always get this error, even when I fixed the path with my windows, it's in the same location. But its ways the path is not valid, can you please help me in this, Thanks in advance.

@lalalanding

hi,

Thank you so much for your reply,

I have done with that, now fro certain images in don't get the depth map, it shows like,

Warning: No face detected

but, still, the image has a good face,

can you please tell me how to overcome it.

I have attached some images below,

I have the same problem. Do you solve it?

I these case, the face detector said then the length will be 0

So I used opencv as a face detector

it works for me
