Hi,Could you please share the training code with me,many thanks.
It'd be difficult to diagnose issues by only checking results, but there could be a couple of steps to figure out which part is causing deterioration.
I have trained multi-view model with PIFu , it's working well, but I don't train a single-view PIFuHD.I sent you an email with more details, but no one replied,maybe the email address shunsuke.satio16@gmalil.com is wrong.
The last name of the email is not correct (also it should be gmail.com). You can resent an email.
I'm very sorry, shunsuke.saito16@gmail.com is the email address I sent,Shall I send an email to this address again?
Yes you can. But why don't you post more details here so that others can also benefit?
Good ieda! I trained 3 view model with pifuHD ,the code is modified from pifu of 3 view,which is working well.The changing detials are as follows:
Figure 1 below is the result of my training with one batch. The training set is the same as the validation set. But the strange thing is that during training,the IOU quickly increased to 0.8, it began to decline, and the reconstructed mesh became worse and worse,as shown in Figure 2,.What's more,the training loss has been declining, and the test loss first decreased and then increased in the same dataset.

Sorry for late response. What you do sounds reasonable to me. One thing is in the multi-view case, cropping of 3 views needs to make sure sampled points are within the cropping of all views. If any views are missing, it might result in unexpected behavior.

In my opinion, pifuhd with multi-view cannot be trained well under the strategy of cropping.After cropping images from different views in the same way, there is no guarantee that the sampling points can be seen from different views at the same time. Am I right?And Did you implement multi-view PifuHD?

I think your understanding is correct. In fact, you have to carefully choose views and points such that these points can be seen from multiple view points. I have not trained multi-view PIFuHD so it might need extra work to get it working.
Many thanks for your kind help !
@SFM2020 Can you share the modified training code for multi-view setup with PIFu?
I trained pifuHD according to the description of your paper with muti-view,but the results are not good as expected.Is there anyting wrong?
