# images.geotrans.PolynomialTransformation2D

2-D polynomial geometric transformation

## Description

A `PolynomialTransformation2D`

object stores information about
a 2-D polynomial geometric transformation and enables inverse
transformations.

## Creation

You can create a `PolynomialTransformation2D`

object in these
ways.

The

`fitgeotform2d`

function, which estimates a geometric transformation that maps pairs of control points between two images.The

`images.geotrans.PolynomialTransformation2D`

function described here. This function creates a`PolynomialTransformation2D`

object using coordinates of fixed points and moving points, or the known polynomial coefficients for the forward and inverse transformation.

### Syntax

### Description

`tform = images.geotrans.PolynomialTransformation2D(`

creates a `movingPoints`

,`fixedPoints`

,`degree`

)`PolynomialTransformation2D`

object and sets the
`Degree`

property. The function estimates the polynomial
coefficients that map control points in the moving image,
`movingPoints`

, to control points in the fixed image,
`fixedPoints`

. You can select control points using the
`cpselect`

function.
