(data, bbox)[source]¶ Determine the background deviation with a box size of bbox. The algorithm steps through the image and calculates the deviation within each box. It returns an array with the pixels in each box filled with the deviation value.
Parameters: data :
ndarray
orMaskedArray
Data to measure background deviation
bbox : int
Box size for calculating background deviation
Returns: background :
ndarray
orMaskedArray
An array with the measured background deviation in each pixel
Raises: ValueError
A value error is raised if bbox is less than 1
