Abstract :
A new fast discrete Radon transform method for enhancement of lines in noisy images is described. It is based on the Fourier slice theorem, with variable length slices to utilise all of the frequency domain data. It is shown that this new method achieves a significant increase in computational speed compared with an existing technique
