Preprocessor.edge_gaussian_filter

Preprocessor.edge_gaussian_filter(template, edge_algorithm, sigma, reverse=False)

Perform Gaussian filterring according to edges in the input template.

Parameters:

templateNDArray

The input atomic structure map.

sigmaNDArray

The sigma value for the Gaussian filter.

edge_algorithmstr

The algorithm used to identify edges. Options are:

‘sobel’	Applies sobel filter for edge detection.
‘prewitt’	Applies prewitt filter for edge detection.
‘laplace’	Computes edges as second derivative.
‘gaussian’	See scipy.ndimage.gaussian_gradient_magnitude
‘gaussian_laplace	See scipy.ndimage.gaussian_laplace

reversebool, optional

If true, the filterring is strong along edges. Default is False.

Returns:

NDArray

Simulated electron densities.
