Preprocessor.kaiserb_filter#
- Preprocessor.kaiserb_filter(template, width)[source]#
Apply Kaiser filter defined as:
\[f_{kaiser} = \frac{I_{0}(\beta\sqrt{1- \frac{4n^{2}}{(M-1)^{2}}})}{I_{0}(\beta)} -\frac{M-1}{2} \leq n \leq \frac{M-1}{2} \text{With } \beta=3.2\]- Parameters:
- templateNDArray
The input atomic structure map.
- widthint
Width of the filter window.
- normalizebool, optional
If true, the output is z-transformed. Default is False.
- Returns:
- NDArray
Simulated electron densities.
