Blurring to a Given Smoothness

Lee Friedman suggested that EPI images should be smoothed to a given smoothness prior to time series analysis.
Tom Nichols believes that the smoothness should be measured locally, not globally. So my idea is to use the method of the previous post, with the mask from 3dAutomask, to
- incrementally blur a little
- test the smoothness in each region
- go back and continue blurring where the image isn't smooth enough yet
