* \brief Linearly interpolate a vector image at specified positions. |
| 28 |
|
* |
| 29 |
|
* VectorLinearInterpolateImageFunction linearly interpolates a vector |
| 30 |
|
* image intensity non-integer pixel position. This class is templated |
| 31 |
|
* over the input image type and the coordinate representation type. |
| 32 |
|
* |
| 33 |
|
* This function works for N-dimensional images. |
| 34 |
|
* |
| 35 |
|
* \warning This function work only for Vector images. For |
| 36 |
|
* scalar images use LinearInterpolateImageFunction. |
