Fitting geometric or algebraic surfaces to 3D data is a pervasive problem in many fields of science and engineering. In particular, ellipsoids are some of the most employed features in computer.

Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed that approximately fits the data. A related topic is regression analysis, which. Least squares support vector machines (LS-SVMs) are very effective methods for regression issue. How to use LS-SVMs to solve the problem of construction B-spline curve in reverse engineering is.
In mathematics, a surface is a generalization of a plane, which is not necessarily flat – that is, the curvature is not necessarily zero. This is analogous to a curve generalizing a straight line. There are many more precise definitions, depending on the context and the mathematical tools that are used to analyze the surface. The mathematical concept of a surface is an idealization of what is meant by surface . Comparison of Corneal Surface Curve Fitting. After acquiring the coordinates from the corneal surface, current research selected according y-coordinates and simulative incident angles in selected x-coordinates to compare three fitting curves. Because one important application of such a mathematical model was to study light by: 4.

For about four years, the (BR) curves and the (SBR) surfaces have been introduced in order to describe any rational curve and respectively any rational surface by means of control nets of mass vectors.
Here, we give sufficient G1and G2continuity conditions between two adjacent (SBR) in. The first book to provide a general framework for both implicit curves and surfaces including their mathematical foundations, data structures, computational methods and algorithms Includes both static and dynamic classes of implicit surfaces.
Curves and Surfaces provides information pertinent to the fundamental aspects of approximation theory with emphasis on approximation of images, surface compression, wavelets, and tomography. This book covers a variety of topics, including error estimates for multiquadratic interpolation, spline manifolds, and vector spline Edition: 1.

When dealing with surface fitting, the author differentiates between techniques for fitting data that lie on a regular mesh (which may be incomplete) and scattered data.
There are traditional unbounded curve fitting techniques-lines of least squares, exponentials, logistic curves, and Gompertz curves.
There is the bounded curve fitting technique of cubic spline interpolation. Beyond these, there is a detailed application of Feigenbaum's graphical analysis from chaos theory, and there is a hint as to how fractal geometry might come into play.
Curve fitting algorithms Cited by: Description. The fitting of a curve or surface through a set of observational data is a recurring problem across numerous disciplines such as applications.
This book describes the algorithms and mathematical fundamentals of a widely used software package for data fitting with tensor product splines. It gives a survey of possibilities, benefits, and problems commonly confronted when approximating with this popular type of function.
Shape preservation of axially symmetric surfaces defined by scattered data is treated in , while  deals with the problem of detecting faults in surfaces on the basis of scattered data.

Since access to computers requires very little training in mathematics, many of these methods may not be easily understood by the great variety of people who are now able to use powerful computing : Paperback.

At the same time mathematical splines, introduced by Schoenberg in the ies, were used by Ferguson at Boeing and Sabin at the British Aircraft Corporation. Generate data with an exponential trend, and then fit the data using the first equation in the curve fitting library of exponential models (a single-term exponential).
Plot the results. x = ()'; y = 2*exp(*x) + *randn(size(x)); f = fit(x,y, 'exp1'); plot(f,x,y).
