Functions
void	drawTransparentLine (cv::Mat &ioImg, const Point2i &a, const Point2i &b, const Color::RGB &color, double alpha=0.5f)
	Draws a line between the two given points using the specified color and the specified line thickness. More...
void	drawCovariance (cv::Mat &ioImg, const Point2i &p, float a, float b, float c, float sigma, const Color::RGB &color, int thickness=1)
	Draws a covariance ellipse into the specified image at position 'p'. More...
template<typename Derived >
void	drawCovariance (cv::Mat &ioImg, const Point2i &p, const Eigen::MatrixBase< Derived > &S, float sigma, const Color::RGB &color, int thickness=1)
	Same as above, where the covariance matrix is specified instead of its coefficients. More...
void	drawInvCovariance (cv::Mat &ioImg, const Point2i &p, float a, float b, float c, float sigma, const Color::RGB &color, int thickness=1)
	Draws a covariance ellipse into the specified image at position 'p'. More...
template<typename Derived >
void	drawInvCovariance (cv::Mat &ioImg, const Point2i &p, const Eigen::MatrixBase< Derived > &Sinv, float sigma, const Color::RGB &color, int thickness=1)
	Same as above, where the inverse covariance matrix is specified instead of its coefficients. More...
