To get the smaller images we used a simple Matlab script to go through each subject’s high-resolution 3D anatomical image […]

PCA has been around for over a century, having first been invented by Karl Pearson in 1901. I have always been taught that PCA was a powerful data reduction technique, allowing a handful of components to represent the […]
