The theory is not difficult the implemetation is a bear. You can use
several types of transforms to find the high contrast areas on each
image. Then you stack the in focus parts and then you assemble them.

If you do this any where near real time it takes a lot of computer
power. If you have to align them as well it gets real hairy real fast.

Just finding the infocus pixels on a high resolution image takes a lot
of processing power. Then having to deal with it in a visual
environment is a headache.

Nothing magic just real hard work.
