I have a series of images in .nii format. Basically these are 3D images that represent the MRI of a brain, in 256 frames.
My questions are:
How do I do feature extraction in such a way that I can have ImageJ output a set of features in maybe a text file that can then be used for machine learning by other programs?
How do I make ImageJ understand these 256 frames all represent a single image? When I try to use some of the analysis options it seems to only do it for a single frame, I need it to do analysis/feature extraction for the entire 3D image as a single unit. Does this have something to do with Stacks? Because it doesn’t let me turn a singular .nii file into a Stack.
Is there a way to do any kind of shape matching or other classification techniques for images within ImageJ itself?
