[Insight-users] Speeding up the evaluation of the itk::Gaussian?

[Dan Mueller]

Hi,

Please select "Build" > "Configuration Manager...". From the "Active
solution configuration" drop down select "Release".

You might be interested in the following MSDN page:
    http://msdn.microsoft.com/en-us/library/cyz1h6zd(VS.80).aspx

Hope this helps.

Regards, Dan
