Creates an ellipse representing the 2D Gaussian distribution. Creates an ellipse representing the 2D Gaussian distribution with mean mu and covariance matrix C. Returns 5 parameters that specify the ellipse. USAGE [cRow, cCol, ra, rb, phi] = gauss2ellipse( mu, C, [rad] ) INPUTS mu - 1x2 vector representing the center of the ellipse C - 2x2 cov matrix rad - [2] Number of std to create the ellipse to OUTPUTS cRow - the row location of the center of the ellipse cCol - the column location of the center of the ellipse ra - semi-major axis length (in pixels) of the ellipse rb - semi-minor axis length (in pixels) of the ellipse phi - rotation angle (radians) of semimajor axis from x-axis EXAMPLE [cRow, cCol, ra, rb, phi] = gauss2ellipse( [5 5], [1 0; .5 2] ) plotEllipse( cRow, cCol, ra, rb, phi ); See also PLOTELLIPSE, PLOTGAUSSELLIPSES, MASKELLIPSE Piotr's Image&Video Toolbox Version 2.0 Copyright 2008 Piotr Dollar.
