Inheritance diagram for nipy.core.image.roi:
Template region of interest (ROI) module
Bases: nipy.core.image.roi.ROI
Create an ROI with a binary function in a given coordinate system.
Parameters: |
|
---|
Return a CoordinateMapROI instance at the voxels in the ROI.
Parameters: |
|
---|---|
Returns: | CoordinateMapROI |
Return a DiscreteROI instance at the voxels in the ROI.
Parameters: |
|
---|---|
Returns: | DiscreteROI |
Bases: nipy.core.image.roi.DiscreteROI
Parameters: |
|
---|
Pool data from an image over the ROI – return fn evaluated at each voxel.
Parameters: |
|
---|---|
Returns: | TODO |
Raises valueerror: | |

Parameters: |
|
---|
Return a feature of an image within the ROI. Feature args are ‘args’, while extra are for the readall method. Default is to reduce a ufunc over the ROI. Any other operations should be able to ignore superfluous keywords arguments, i.e. use extra.

Pool data from an image over the ROI – return fn evaluated at each voxel.
Parameters: |
|
---|---|
Returns: | TODO |
This is the basic ROI class, which we model as basically a function defined on Euclidean space, i.e. R^3. For practical purposes, this function is evaluated on the range of a Mapping instance.
Parameters: |
|
---|
Bases: nipy.core.image.roi.CoordinateMapROI
An ROI for an entire coordmap. Save time by avoiding compressing, etc.
Parameters: |
|
---|
Parameters: | image : image.Image |
---|---|
Returns: | None |
Ellipse determined by regions where a quadratic form is <= a. The quadratic form is given by the inverse of the ‘form’ argument, so a sphere of radius 10 can be specified as {‘form’:10**2 * identity(3), ‘a’:1} or {‘form’:identity(3), ‘a’:100}.
Form must be positive definite.

Return a CoordinateMapROI from an array (data) on a coordmap. interpolation. Obvious ways to extend this.
