SplineLibrary provides the functionality for building, calibrating, and evaluating different kinds of splines.
SplineLibrary implements the functionality behind spline design, spline constructions, customization, calibration, and evaluation of a wide variety of spline types and basis functions.
SplineLibrary achieves its design goal by implementing its functionality over several packages the perform the following:
· Spline Calibration Framework: Schematic spline segment/span partitioning, elastic/inelastic entity-variate separation, mathematical calibration formulation framework with constraints/boundary incorporation, sensitivity Jacobian estimator setup, Hard/Soft (Truthness/Smoothness) partitioning.
· Shape Preserving Spline Suite: B-splines, Polynomial Splines and Variants (Bernstein, Kaklis-Pandelis, Manni), Integrated Tension Splines (exponential/hyperbolic), partitioned tension splines (explicit shape control using rational splines).
· Space Spline Curves: Hermitian, Catmull-Rom, Cardinal Cubic, Space Loops.
. B Splines: Polynomial Koch/Loche/Kvasov Tension B Splines Monic/Multic Sequence Generation and Setup.
· Spline Calibration: Explicit segment formulation frame work, Optimizing shape preserving splines, curvature/segment-length (or criterion-defined) penalty minimizing mu-splines, segment/span self-Jacobian, quote-Jacobian, and micro-Jacobian.
. Spline Smoothing Schemes: Akima, Bessel, Harmonic, Hyman83, Hyman89, Kruger, Preuss, Hagan-West, and Preuss schemes.
. Regression Splines: Curveture/Length Penalizing and Best-Fit Splines.
· Spline Evaluation: Metric'ed evaluation of monotonicity, convexity, smoothness, smoothness, locality, and approximation order.
· Spline Extensions: Variational Smoothing, density smoothing technique, alternate smoothener customization extension, multi-dimensional (including thin plate) splines.
The user Guide, the API Javadoc, and the samples are also available here.
