## General Information

- Type: CLP
- Category: VectorField

- Description: Compute the exponential of a vector field. Basically it assumes the input vector field is a logarithm, and therefore the exponential reduces to performing a number of compositions of the input vector field with itself.

## Usage

### Parameters

Label | Type | Flag / Index | Default value / Channel | Description |
---|---|---|---|---|

Parameters | ||||

N composition | integer | N_compose | 10 | 2^N steps decomposition for log-exp |

Downsample/Resample | boolean | DSRS | false | DownSample / Resample VF |

Exanding Iterations | integer | N_it | 0 | Number of expanding iterations |

Sigma | float | sig_decrease | 0 | Sigma for the exponential decrease |

Smoothing radius | integer | V_radius | 3 | Smoothing radius |

IO | ||||

Input Vector Field | image (fileExtensions=".mhd" type="vector") | index 0 | input | Input Vector Field |

Output Vector Field | image (fileExtensions=".mhd" type="vector") | index 1 | output | Output Vector Field |

### Examples

Input VF range is from 0 to 0.04, while output image range is from 0 to 5.1.
