Member Function Documentation

int mimas::pol_locator_hough::calcGaussBoxSize	(	double	sigma,
		double	accuracy
	)			[protected]

as in hough_transform.cc.

used to calculate the size of the gaussian dist. required to represent a curve with sigma 'sigma' to the accuracy given

void mimas::pol_locator_hough::setLocation	(	int	x,
		int	y,
		double	ca,
		double	sa
	)			[protected]

make an entry at position x,y with weight w and angle a ca = w*cos(a) and sa = w*sin(a)

void mimas::pol_locator_hough::initFastGauss	(	double	sigma,
		double	precision
	)			[protected]

in order to plot gauss points faster, we calculate the required distribution first.

this assumes that all points will be equally accurate, but it's fast.

void mimas::pol_locator_hough::addGaussPointFast	(	const Vector &	posn,
		double	w,
		double	angle
	)			[protected]

plot a point as position posn with weight 'w' and angle 'angle' replaced by addEntry now 200212
