Hi all: Does anybody know What form of image should be passed in？ thanks

There are several algorithms for estimating the MTF based on an image, the slanted edge method, LSF method, PSF method, and so on, as well as some more advanced techniques for other targets (Thurman's Siemens' Star method, say).

The estimation process is out of scope for prysm and there are no functions in the library for computing MTF from an image of anything but a point spread function.
