MeasureRadius¶
Measures intensity decays at spcified points in the data.
-
measure_radius(source, points, fraction=None, value=None, max_radius=100, method='sphere', default=inf, scale=None, return_radii=True, return_radii_as_scalar=True, return_indices=False, processes=None, verbose=False)[source]¶ Measures a radius via decay of intensity values for a list of points.
Arguments
- sourcearray
Source for measurement.
- pointsarray
List of indices to measure radis for.
- fractionfloat or None
Fraction of center intensity that needs to be reached to detemrine the radius. If None, value needs to be given.
- valuearray or float or None:
The value below which the inensity has to fall to measure the radius from the center pixel. If array, it has to be the same size as the points. If None, fraction has to be given.
- max_radiusint or tuple of ints
The maximal pixel radius to consider in each dimension. The larger the slower the measurement.
- defaultnumber or None
Default value to use if no radius was detected.
- scale: tuple or float
An optional scale in each direction to determine the distance.
- return_radiibool
If True, return the radii measured.
- return_radii_as_scalarbool
If True, returnt the radii as single floats, otherwise a radius for each dimension.
- return_indicesbool
If True, return the indices of the search which allows to idenitfy the pixel at which the radius condition was met.
- processesint or None
Number of processes to use.
- verbosebool
If True, print progress info.
Returns
- radiiarray
Array of measured radii if return_radii is True.
- indicesarray
Array of measured indices at which the radius detrection condition is met.
-
search_indices_rectangle(radius)[source]¶ Creates all relative indices within a rectangle.
Arguments
- radiustuple or float
Radius of the sphere of the search index list.
Returns
- indicesarray
Array of ints of relative indices for the search area voxels.
