Transfer Learning using PointNet #241

Open dhirajsuvarna opened 4 years ago

Hi @charlesq34,

I wanted to know if it is possible to use Transfer Learning using PointNet Architecture.

I would request someone to guide me in achieve this or guide me in the right direction.

Hi! were you able to do it? Can you please point me to useful resources?

@shivammalviya712 , I found out the transfer learning using PointNet is a bit tricky and difficult as it depends on the orientation of the 3D Model. So, its best not to use in this case.

Also, PointNet doesn't need exuberant amount of data to get good accuracy, so you there is no need for transfer learning.

Hi! @dhirajsuvarna

depends on the orientation of the 3D Model.

Do you think it is better to always use mesh in the same orientation? I was trying segment humans body with PointNet passing examples un differents poses and orientation, and the results are not the best

Thanks!

@CristianContrera95 - yup, you need to have models oriented along a single directions. PointNet is not rotation invariant.
