Hi @dhruvrajsaharan

You can use my other repository SMPL-Fitting to fit the SMPLX model to the SPRING scans. You'll need landmarks for the fitting process however. The landmarks are used to initialize the fitting (since the scan and SMPLx can be anywhere in space) as well as to stabilize the fitting process.

In theory you could skip using the landmarks for the initialization, if you pre-align the scan and SMPLX model. If I'm not mistaken, the SPRING scans are all aligned in the same way, so by aligning the SMPLX with a single scan, you could use the same initial alignment for each scan.

Regarding the stabilization of the fitting process, it could work without using the landmarks, but you'll need to play around with the loss weights from the loss_weight_configs.yaml.

To the best of my knowledge there is no open-source approach that finds the landmarks unfortunately.
