Switch to OpenPose from LSP about muvs

[YinghaoHuang91]

This is the major body joints to quickly initialize the body orientation. The indices (3, 4, 9, 10) are 1-st based, thus -1 makes them 0-based. Actually with enough views this step can be safely ignored.

@YinghaoHuang91 Thank you very much for the reply!
Then what is the Head_VID mean?

MuVS/Code_TF/util.py

Line 29 in 199f51e

HEAD_VID = 411

Does it mean the head top vertices ID of SMPL?
I saw in line 27 you map the LSP keypoint to SMPL's, and the headtop keypoint was not read into line SMPL_JOINTS_IDS,

MuVS/Code_TF/util.py

Line 27 in 199f51e

SMPL_JOINT_IDS = [8, 5, 2, 1, 4, 7, 21, 19, 17, 16, 18, 20, 12]

how did you deal with the headtop keypoint?
I have some problem about how do map the openpose nose point to SMPL jaw.

The HEAD_VID is used in Line 41 of file "smpl_batch.py". Yes it's the SMPL vertex index to act as the proxy for head 2D landmark. Since SMPL doesn't have facial landmarks, one way is to manually pick the close vertices. You can do the same thing for other 2D landmarks if you want to stick with SMPL. Or you can try other more recent version of SMPL, like SMPL-X or STAR.

thanks for quick reply!
I got this, so where can I check these VIDs of SMPL vertices? e.g. I want to find the nose, eyes and ears for openpose corresponding.
I considered about using SMPL-X, but their works mainly used python3.6....

I found the nose_vid in smplx repo's smpl-h vid doc, but I haven't test it.
