Scale variance of the generated meshes #93

Closed Ramya0694 closed 4 years ago

Ramya0694 commented 4 years ago

I was trying to run the SMPL-X model on an image and a doubly scaled version of the same image. However, I do not see similarly scaled meshes upon running the model on them. Is the model scale invariant or is there something that I'm missing here?

@Ramya0694 The model is not scale invariant. If you simply double or halve your resolution, the initialization will simply place the body closer or farther so that the projection of the hips and shoulders matches their image location.
