On the Radon transform and linear transformations of images
We present a novel original method for estimating and recovering a general geometric
transformation which is applied to an image. Our main tool is the Radon Transform; we …

Using Few Radon Projections to Recover 3-D NMR Spectrum
FI Hjouj - Journal of Mathematical Sciences & …, 2017 - journals.atlas-publishing.org
Given a regular binary function f on R 2 with compact support D, we use translation to form a
new binary function g from f so that the image representation of g (x, y) is made up of non …
