radon - Radon transform

Calling Sequence

R = radon(im,theta)

Input Parameters

Output Parameters

Description

The Radon transform is the projection of the image intensity along a radial line oriented at a specific angle

Examples

   im = zeros(100,100);
   im(25:75,25:75) = 1;
   r=radon(im);
   imshow(r,[])

   im2 = iradon(r);
   xbasc()
   imshow(im2,[])
