i am currently working on applying z transform for images. in matlab, there is a function called ztrans in symbolic math toolbox for applying z transformation for symbolic expressions or matrix of symbolic expressions. could any one please suggest me how to apply z transformation for images, just as we would use fft or dwt2 for images?

doc czt
You can apply czt on each row followed by applying it on each column.

Thanks for your reply. And i would also like to know how to perform the inverse for this czt as there is no function in matlab for computing the inverse czt?
