PyDDM.ddm_calc.generate_mask¶
-
generate_mask(im, centralAngle, angRange)¶ Generates a mask of the same size as im to avoid radially averaging the whole DDM matrix.
If the DDM matrix is not to be radially averaged, we can use a mask to average values of the matrix only in some angular range around a central angle.
- Parameters
im (ndarray) – Image (2D) of same size you want the mask to be.
centralAngle (float) – Central angle of the angular range to average over
angRange (float) – Range to overage over.
- Returns
mask – Mask with 1s corresponding to the angular region specified and 0s elsewhere.
- Return type
ndarray
