[Insight-users] Distance transform in a hurry

[Benjamin King]

Hello,

in case you need a fast (squared) euclidean distance transform, you  
should probably give the one in http://hdl.handle.net/1926/196 a  
shot. I have just uploaded a new revision (the bigger archives) that  
is playing well with L1 cache and is able to use OpenMP in case you  
pass gcc the -fopenmp flag (or whatever enables OpenMP in your  
compiler).

I have had measured 20-30 times speedup in comparison to  
DanielssonDistanceMapImageFilter, but depending on your hardware, the  
typical image sizes you have and availability of OpenMP to you, your  
mileage will vary.

If you find good results or areas for improvement, don't hesitate to  
write a review. I promise that I will not wait four years again to  
come back to it ;-)

cheers,
	Benjamin
