Vector Field Exponential

General Information

  • Type: CLP
  • Category: VectorField
  • Author: Nicolas Duchateau
  • Contributor: Xavi Planes
  • Contact: xavier.planes at upf.edu
  • 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
VF extension
Exanding Iterations integer N_it 0 Number of expanding iterations
Sigma float sig_decrease 0 Sigma for the exponential decrease

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.
