Fast algorithms and efficient GPU implementations for the Radon transform and the back-projection operator represented as convolution operators
Fredrik Andersson, Marcus Carlsson, Viktor V. Nikitin
The Radon transform and its adjoint, the back-projection operator, can both be expressed as convolutions in log-polar coordinates. Hence, fast algorithms for the application of the…
