<div class="fragment"><pre class="comment"> Runs descriptor on a subset of cuboids or images to get PCA coefficients.
INPUTS
I - 3D array of images or 4D array of cuboids
imdesc - descriptor to apply to each image or cuboid
k - number of PCA coefficients to use [note: k can be later reduced]
OUTPUTS
imdesc - new imdesc with PCA information</pre></div>
