Coherent radon transform
Did you know?
WebThe generalized Radon transform integrates (stacks) the data along curved surfaces, whereas the classical Radon transform stacks along planar surfaces (Beylkin, 1987). In practice, the technique is applied in the same way that the Fourier transform and slant stacking are used as dip filters for coherent noise with linear moveout. WebThe Hough transform (HT) is an efficient shape detector that maps straight lines into a two-parameter feature space. Recently it has been pointed out that the forward Radon transform (FRT), well known from the theory of computed tomography, and the HT are equivalent for binary images. In this paper, analog coherent optical implementation of …
