- kikuchipy.pattern.get_dynamic_background(pattern: ndarray, filter_domain: str = 'frequency', std: None | int | float = None, truncate: int | float = 4.0) ndarray #
Get the dynamic background in an EBSD pattern.
The background is obtained either in the frequency domain, by a low pass Fast Fourier Transform (FFT) Gaussian filter, or in the spatial domain by a Gaussian filter.
Data type is preserved.
Whether to obtain the dynamic background by applying a Gaussian convolution filter in the
Standard deviation of the Gaussian window. If not given, a deviation of pattern width/8 is chosen.
Truncate the Gaussian window at this many standard deviations. Default is
The dynamic background.
