What does the radon transform do?
The Radon transform is an integral transform whose inverse is used to reconstruct images from medical CT scans. A technique for using Radon transforms to reconstruct a map of a planet's polar regions using a spacecraft in a polar orbit has also been devised (Roulston and Muhleman 1997).
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 .
Is the radon transform linear?
e Radon transform is in fact a linear transformation, which can be seen by the fol- lowing calculations.
