Abstract:
1. A computer-implemented method for using a degraded first image to generate a second image, the second image being a stationary point of an Euler's elastica energy defined using the first and second images, the method comprising finding a stationary point of an augmented Lagrangian function, obtained from the Euler's elastica energy using a plurality of supplementary variables and Lagrange multipliers; wherein the Euler's elastica energy is of the form: where: (i) a, b and η are parameters which are greater than zero, and s is a parameter which is greater than or equal to 1; (ii) the first image is a set of values u (iii)  denote respectively the integrals over the sets of points Ω and Γ.
