I'm not implying my obvious approach is better and that anyone is stupid for not doing it instead. People downvoting me for implying that are not being charitable. On the contrary, the fact that they did not use it is good evidence that it is inadequate, given they spent a long time on the problem and I'm sure simpler solutions occurred to them. So I'm agreeing with you here. I'm just expressing interest it knowing why it isn't adequate. Though for what it's worth I do work a lot with image processing (of trapped atoms though, not biological samples), so my first thoughts are also coming from someone who's spent a decent chunk of time considering these things.
