Great responses!
After some further thought, I will be severely decreasing the number of
landmarks for several reasons.
Thank you all for your help!

Hello,
I am new to the field of morphometrics and have a (potentially very
ignorant) question.
I have images that contain a deformable body and a rigid body. The
images are rigidly registered to align the rigid bodies. The
deformable bodies are described by ~5,000 points which are matched
across each image. I believe my data is then comprised of the 3D
coordinates of the ~5,000 points of the deformable body depicted in
each image.
Can I treat these points as landmarks and perform a very
high-dimensional (~15,000-D) PCA? Is there any "curse of
dimensionality" with this method?
I appreciate your help.
