The radon function computes the Radon transform, which is the projection of the image intensity along a radial line oriented at a specified angle. I for the angle theta degrees. If theta is a scalar, the result R is a column vector containing the Radon transform for theta degrees. If theta is a vector, then R is a matrix in which each column is the Radon transform for one of the angles in theta .
R has n rows.
This number is sufficient to compute the projection at unit intervals, even along the diagonal. All other inputs and outputs are of class double . Two-Dimensional Signal and Image Processing. Bracewell, Ronald N. Two-Dimensional Imaging. Prentice Hall, 1995.
