Function Documentation

guessGauss2D_ang()

template<typename realT >

int mx::math::fit::guessGauss2D_ang	(	realT &	Ag,
		realT &	xg,
		realT &	yg,
		realT &	xFWHM,
		realT &	yFWHM,
		realT &	angG,
		mx::improc::eigenImage< realT > &	im,
		realT	maxWidth,
		realT	widthWidth,
		realT	nAngs,
		realT	xg0,
		realT	yg0
	)

Form an estimate of the parameters of an elliptical Gaussian from a 2D image.

Note that this assumes that there is no constant value (i.e. it is zero-ed).

Returns

0 if successful
