pysteps.utils.tapering.compute_window_function¶
- pysteps.utils.tapering.compute_window_function(m, n, func, **kwargs)¶
Compute window function for a two-dimensional rectangular region. Window function-specific parameters are given as keyword arguments.
- Parameters
- m: int
Height of the array.
- n: int
Width of the array.
- func: str
The name of the window function. The currently implemented functions are ‘hann’ and ‘tukey’.
- Returns
- out: array
Array of shape (m, n) containing the tapering weights.
- Other Parameters
- alpha: float
Applicable if func is ‘tukey’.
Notes
Two-dimensional tapering weights are computed from one-dimensional window functions using w(r), where r is the distance from the center of the region.
