# VF DownSample CLP

From user's Wiki!

## General Information

- Type: CLP
- Category: VectorField
- Author: Nicolas Duchateau
- Contributor: Xavi Planes
- Contact: xavier.planes at upf.edu
- Description: Downsample/resample a 3D vector field. By default the program reduces the resolution by 50% in each dimension (so a total reduction by a factor of 8), maintaining the origin of the input vector field.

## Usage

### Parameters

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

Parameters | ||||

Sigma | float | sig_decrease | 100 | 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 |

Reference VF | image (fileExtensions=".mhd" type="vector") | RS | input | ReSample, VFfilename used as reference for size |

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

### Examples

When resampling a vector field using a reference image of spacing 2, 2, 8, the output vector field will have spacing 2, 2, 8.
