How to train and predict without background ?

[Jiakui]

Dear author,

We are working on a project that we need to get the mesh of the object without background. I noticed that , by default, the input of the demo code do not remove the background. Right now I want to train my object without background. So my question is: should I fill the backgound region to black or white after image matting ? Should I turn the image into RGBA and the alpha channal corresponding to the opacity ?

Thanks!
