How to calculate a 2D rotation vector with PCA?
4 views (last 30 days)
Hi all. I have two dataset (n x 2 matrix) in 2D space and I know their PCA matrices. PCA1 = [0.9981 -0.0622; 0.0622 0.9981], PCA2 = [0.5617 0.8273; 0.8273 -0.5617]
And I want to rotate one of these dataset and make them to be registered. How can I get a rotation vector?
