void Ellipse::SetGaussianFilterRange	(	const double &	sigmaX,
		const double &	sigmaY,
		const double	F = 9.0
	)

Assumes ellipse to be a certain iso value line on a 2D gaussian without cross correlation (no rotation).

Gaussian is g(x) = 1/N exp(-0.5 x^t Q x). This ellipse will be Q = I*(1/sigmaX^2 , 1/sigmaY^2) Ellipse calculated has the implicit form: x^t Q x - F = 0.
