How to do Radon transform matlab?
R = radon( I ) returns the Radon transform R of 2-D grayscale image I for angles in the range [0, 179] degrees. The Radon transform is the projection of the image intensity along a radial line oriented at a specific angle. R = radon( I , theta ) returns the Radon transform for the angles specified by theta .
What does radon do in Matlab?
The radon function computes projections of an image matrix along specified directions. A projection of a two-dimensional function f(x,y) is a set of line integrals. The radon function computes the line integrals from multiple sources along parallel paths, or beams, in a certain direction.
What is inverse Radon transform?
Inverse Radon Transform Definition. The iradon function inverts the Radon transform and can therefore be used to reconstruct images. As described in Radon Transform, given an image I and a set of angles theta , the radon function can be used to calculate the Radon transform. R = radon(I,theta);
