There are some weird things？

[liqiang311]

Thanks for your trained model, and I run it on my own video.

As a result, there are some weird things on the image, as shown in the figure.

What's that? Can you help me?

Hi!
As far as I see those images/frames contain artifacts due to compression, which of course can be seen as noise, but it was not a type of degradation that was in my training set. Maybe that's the explanation.
I will try to denoise those two images on my pc and see if there are differences.

[liqiang311]

Yes, you are correct, the sequence I am using is coded and there is quantization noise.

I have used the original sequence to test, and the bad phenomenon still exists, but it is much better.

So, I've tried your noisy input and I don't get any strange output, tested with both checkpoint I provide.
Which tensorflow version are you using?

Thank you for your testing.

• Python version: 3.6.4
• Tensorflow version: tensorflow-gpu (1.4.0)

I only change the "xrange" to "range" in code. And I am running a series of images.

The only think I can try is to use your data on my machine, attach your files here if you want.

Hi, thanks a lot for the trained model!

I too have the same issue. Is it may be because the model is overfitting, as it has not seen these artefacts in the training data?

• Python 3.6.7
• tensorflow==1.12.0

(I am sending you the images via mail, as I cannot put it up online). Please also note that I can see these artefacts in all the frames!

Thanks!

If you use the gaussian trained checkpoint you won't have any of those weird results.
Just run it with: python main.py --ckpt_dir=./ckpt_vidcnn-g

Thank you, I'm having a problem with running
python main.py --ckpt_dir=./ckpt_vidcnn-g
so I've opened this new issue.

Hi I‘m so interested in your work and I meet the same problem，it's the input png which is compressed will cause these artifacts？
