Member Function Documentation

process()

void EyeTracker::process	(	cv::Mat &	eyeimg,
		double	pupell[5],
		bool	debugdraw = false
	)

Process grayscale byte image from camera.

Note: we will draw the detected ellipse and a few more things in the image.

pupell will be filled with the pupil ellipse params, in the order used by opencv to draw ellipses: a, b, cx, cy, theta.
