This plugin uses the Helmholtz equation to estimage the wavelength of a harmonic image. Bob Dougherty 8/27/2005. Formerly named Muscle Tone. Version 1 Oct. 12, 2011 Fixed a bug that caused bad averaging and possibly index out of bounds for non-square images Version 2 Oct. 15, 2011 Hardwired choices for filtering radii and averaging tolerances. Added checkboxes to select outputs. Added support for ROIs. Added progress bar for averaging. Improved handling on invalid points. Weighted average for phi.
