About 3D Mesh generator. about gcl HOT 11 CLOSED

1. It's ok to use other recent 3D mesh generator. But make sure that mesh color is grey, not other colors (blue).
2. You are right. I just used their pretrained 3D mesh model on ReID datasets.

Thank you for quick reply.
I have another question.

Does the mesh rendered image size should be exactly same as the original image size??

For example, below is the original re-ID dataset image which is size of 128x64.

But I get the mesh render image below which is size of 224x224.

Should it be exactly same size 128x64??

from gcl.

It's better to conserve the original size 128x64. Or, al least, the same height width ratio, for example, 256x128.
Otherwise, it will become hard to realize the image reconstruction with GAN.

from gcl.

Oh, I see..

This is the example of your mesh results.

This is the results that I have created with size 224x224, using recent mesh generator

and I just resized it to 128x64 to make it same with original image like this.

The color looks a little bit different which I can't find exact rgb value of yours.
Should this grey color be okay?
and I'm not exactly sure if it is okay to just resize it.

from gcl.

I used [0.87843137254, 0.87843137254, 0.87843137254] as rgb values.

Your resized meshes seem to be OK. You can try with your meshes.

Thanks,

Lastly, for some cases, I keep getting these lines below the rendered person meshes.

Do you think this will affect negatively on your network??

from gcl.

I'm not sure. When I clicked to zoom in your mesh images, I could not see any lines.

from gcl.

Why should image and mesh size should be 256x128??
Is it because your model is trained in 256x128 images and meshes??

If I want to use other size, for example (374x128) size image to use generate,
Do I need to resize all meshes and images to (374x128) then train the
Generator from the beginning?

Thanks.

256x128 is a common image size setting in ReID community. We follow this setting to conduct fair comparison with previous ReID methods.

please any idea how I can change the mesh color? mines are yellow. And am using https://github.com/russoale/hmr2.0

from gcl.

@khadijakhaldi You may change the color via https://github.com/akanazawa/hmr/blob/f149abeb0a7e2a3412eb68274a94a9232f7cb667/src/util/renderer.py#L18
