(mask, func, **kwargs)¶ Compute window function for a two-dimensional area defined by a non-rectangular mask. The window function is computed based on the distance to the nearest boundary point of the mask. Window function-specific parameters are given as keyword arguments.
Parameters: - mask : array_like
Two-dimensional boolean array containing the mask. Pixels with True/False are inside/outside the mask.
- func : str
The name of the window function. The currently implemented function is ‘tukey’.
Returns: - out : array
