Image projections using MATLAB

How can I generate a set of image projections using MATLAB?

开发者_运维知识库

I have a 256x256 image. I want to get all 180 projections ranging from 0 degree to 180 degree projection angle.

Is there a way to do that in MATLAB?

You can use RADON

theta = 0:180; %# angle from 0 to 180 degrees
R = radon(yourImage,theta);

Each column of R corresponds to one angle from the list in theta
