* \brief Base class for all ITK function objects |
| 29 |
|
* |
| 30 |
|
* FunctionBase is the base class for ITK function objects. Specifically, |
| 31 |
|
* the abstract method Evaluate() maps a point from the input space to a point |
| 32 |
|
* in the output space. |
| 33 |
|
* |
| 34 |
|
* Subclasses must override Evaluate(). |
| 35 |
|
* |
| 36 |
|
* This class is template over the input (domain) type and |
| 37 |
|
* the output (range) type. |
