PIXIE initialization

[Bai426]

Thanks for your great work. I am reproducing your work with h3ds dataset. But I am facing one problem in multi-view optimization (https://github.com/SamsungLabs/NeuralHaircut/tree/main/src/multiview_optimization) : it says that we need an initialization with PIXIE for shape, pose parameters and save it as a dict in initialization_pixie file.

When I go to PIXIE repository, I am wondering which single image can be used for the initialization or all the multi-view images have to be used. Also, how to get initialization_pixie file is unclear. Thank you!

Best, Mike
