SPIM registration almost supports integral images for fast processing of data from the zeiss scope
integral image based segmentation works
added choice to do a gauss fit
Improved the choice for gaussian localization
better output text
difference-of-mean performance doubled
selective gauss fit for only true correspondences works
integral based difference-of-mean segmentation works
added specialized implementation of the integral image for 3d float->long based on arrays
difference-of-mean does quadratic fit as well
updated dialog to reflect new option
changed default registration type to difference-of-mean
working on the content-based fusion
