- kikuchipy.pattern.get_image_quality(pattern: ndarray, normalize: bool = True, frequency_vectors: Optional[ndarray] = None, inertia_max: Union[None, int, float] = None) float #
Return the image quality of an EBSD pattern.
The image quality is calculated based on the procedure defined by Krieger Lassen [Lassen, 1994].
Whether to normalize the pattern to a mean of zero and standard deviation of 1 before calculating the image quality (default is
Integer 2D array assigning each FFT spectrum frequency component a weight. If not given, these are calculated from
fft_frequency_vectors(). This only depends on the pattern shape.
Maximum possible inertia of the FFT power spectrum of the image. If not given, this is calculated from the
frequency_vectors, which in this case must be passed. This only depends on the pattern shape.
Image quality of the pattern.
