WebOur MATLAB code is comprised of 4 main functions: go.m, projfilter.m, back.m, and proj.m. Our file, proj.m, takes an image in matlab format and pads it with enough zeros so that when the image is rotated, none of the original picture is lost. Then it performs line integrals for different thetas around the image to create projections of the image. http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/images/iradon.html

Here, we try to cut … Webiradon uses the filtered backprojection algorithm to perform the inverse Radon transform. The filter is designed directly in the frequency domain and then multiplied by the FFT of the projections. The projections are zero-padded to a power of 2 before filtering to prevent spatial domain aliasing and to speed up the FFT.
