auto_sigma_prior needs to depend on magnification
Created by: cabouman
The current versions of auto_sigma_prior()
, auto_sigma_x()
, and auto_sigma_p()
were directly ported from SVMBIR, so they do not depend on magnification
. I think this means that the value of the estimated values of sigma_x
and sigma_p
will be wrong for large values of magnification
. However, we will want to double check this first by running some examples.
We will probably need to replace line 183 with:
typical_img_value = np.average(sino, weights=sino_indicator) / (num_det_channels * delta_pixel_detector/magnification)
Once this is tested, we will want to port these routines to SVMBIR since with the fan
geometry SVMBIR also has magnification
.
