Parameters

This section documents the parameters recognized by this task (if any).

ParameterMand Type Default Constraints
imagesetyesdatasetdummy_default 
The input image dataset.
 
outputstylenotypecartesiancartesian|polar
This controls the style of the output. If outputstyle=`cartesian', the two output images store the x and y components of the gradient; if outputstyle=`polar', the two output images store the magnitude and azimuth of the gradient.
 
xgradimagesetnodatasetxgrad_image.ds 
If outputstyle=`cartesian', this dataset is used to store the x component of the gradient.
 
ygradimagesetnodatasetygrad_image.ds 
If outputstyle=`cartesian', this dataset is used to store the y component of the gradient.
 
gradsizeimagesetnodatasetgrad_size_image.ds 
If outputstyle=`polar', this dataset is used to store the magnitude of the gradient.
 
gradazimuthimagesetnodatasetgrad_azim_image.ds 
If outputstyle=`polar', this dataset is used to store the azimuth (from 0 to $\pi$) of the gradient.
