get_dynamic_background#
- kikuchipy.pattern.get_dynamic_background(pattern: ndarray, filter_domain: str = 'frequency', std: None | int | float = None, truncate: int | float = 4.0) ndarray [source]#
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.
- Parameters:
- pattern
EBSD pattern.
- filter_domain
Whether to obtain the dynamic background by applying a Gaussian convolution filter in the
"frequency"
(default) or"spatial"
domain.- std
Standard deviation of the Gaussian window. If not given, a deviation of pattern width/8 is chosen.
- truncate
Truncate the Gaussian window at this many standard deviations. Default is
4.0
.
- Returns:
dynamic_bg
The dynamic background.
