Creates a binary image of an ellipse. Creates a binary image of size (mRows x nCols), with all pixels set to 0 outside the ellipse and 1 inside. The ellipse is given by 5 parameters, a semimajor axis of ra, a semminor axis of radius rb, angle phi (in radians), and center (cRow,cCol). An alternative method of specifying the ellipse parameters is in terms of a 2D Gaussian. For more info on how a Gaussian relates to an ellipse see gauss2ellipse. USAGE mask = maskEllipse( mRows, nCols, cRow, cCol, ra, rb, phi ) mask = maskEllipse( mRows, nCols, mu, C, [rad] ) INPUTS [version 1] mRows - number of rows in mask nCols - number of columns in mask 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 (in radians) of semimajor axis to x-axis INPUTS [version 2] mRows - number of rows in mask nCols - number of columns in mask mu - 1x2 vector representing the center of the ellipse C - 2x2 cov matrix rad - [2] Number of std to create the ellipse to OUTPUTS mask - created image mask EXAMPLE mask = maskEllipse( 200, 200, 40, 100, 20, 15, pi/4 ); figure(1); im(mask); [mu,C] = imMlGauss( mask, 0, 2 ); See also PLOTELLIPSE, GAUSS2ELLIPSE, MASKCIRCLE, MASKGAUSSIANS, IMMLGAUSS Piotr's Computer Vision Matlab Toolbox Version 2.40 Copyright 2014 Piotr Dollar.
