Mean limb offset and FK script #6

Closed alecda573 closed 3 years ago

alecda573 commented 3 years ago

Hi Saeed,

Where can I find the mean limb offsets and did you guys decide to make public an FK script to convert the Exp maps to the join locations?

Thanks.

Hi,

If you are working on the AMASS representations, the FK is here. If you are going to have the same skeletal size for all samples, you should set betas to all zeros (or your custom shape parameters) inside this function. Also make sure that you install all AMASS dependencies. For the V3D I haven't written any FK yet. Hopefully soon.

@saeed1262 Thanks for this response. Can you answer a couple more questions possibly?

1) The amass_fk function is calling for a npz file path, but no npz file are in the database, what are these suppose to be exactly? 2) If the npz files are not available, what is the key 'poses' referring to in the .mat files? Is this the ExpMaps?

Hi, The npz files are original AMASS versions of our dataset which should be downloaded separately here Please follow this tutorial

The mean limb offsets are inherently in the body model. But shouldn't be hard to extract it.

@saeed1262 One other question, at what hz is the data recorded in the npz format, 30 or 120?

saeed1262 commented 3 years ago

It is 120. But the video data fps is 30.
