:::Issue recreated from Jira issue HZN-75:::

Imported from https://bitbucket.org/gsttmri/hazen/issues/76/spres-use-curve-fitting-for-esf-and Use a curve fitting algorithm, perhaps cubic spline, to estimate ESF.The current algorithm rounds to a nearby pixel (often not the closest) at several points (issues #69, #72, #75), reducing the overall accuracy and resolution of the MTF, and giving more weighing to the points furthest from the edge.Fitting a smooth curve to the ESF and calculating the LSF and MTF from these fitted values may improve both accuracy and resolution.

How does this differ from https://github.com/GSTT-CSC/hazen/issues/68 ?
