Geometric correction through complex interpolation
نویسنده
چکیده
A method for the correction of images that are subject to spatial warping is presented. The correction method applies to twodimensional images and employs the construction of a complexvalued interpolating polynomial. The construction is based on defining a set of points in an image whose desired location is known. The coefficients of the polynomial are shown to satisfy a recursion relation that simplifies implementation and improves evaluation efficiency. Results are presented for a twodimensional slice from a magnetic resonance image.

متن کاملAn Optimal G^2-Hermite Interpolation by Rational Cubic Bézier Curves
In this paper, we study a geometric G^2 Hermite interpolation by planar rational cubic Bézier curves. Two data points, two tangent vectors and two signed curvatures interpolated per each rational segment. We give the necessary and the sufficient intrinsic geometric conditions for two C^2 parametric curves to be connected with G2 continuity. Locally, the free parameters w...
متن کاملReduced basis approximation for shape optimization in thermal flows with a parametrized polynomial geometric map
Reduced basis approximations for geometrically parametrized advection-diffusion equations are investigated. The parametric domains are assumed to be images of a reference domain through a piecewise polynomial map; this may lead to nonaffinely parametrized diffusion tensors that are treated with an empirical interpolation method. An a posteriori error bound including a correction term due to thi...
