Today:
	Stack alignment experiment

How could we make it faster?
	Use C
	Reduce the resolution 
		Test example with synthetic data
	Use a smaller area of the image
	Landmarks?  Weirdly hard to do in biological images
		They all shift

Tests:
	0.  Synthetic data test
	1.  C/pthreads
	2.  Subset

Another test, probably not in class:	
	GPU-based comparison
	Should be faster
	We could use an opencl example from a long time ago and probably make this work

Lab today:
	These need to ease up a bit in difficulty!
	We'll do an old CS108 test, with the ventricle counter
	Are we looking at a nuclear or plexiform image?
