Rescale intensities in an EBSD pattern.

Pattern max./min. intensity is determined from out_range or the data type range of numpy.dtype passed to dtype_out.

This method is based on skimage.exposure.rescale_intensity().

Parameters:
pattern

EBSD pattern.

in_range

Min./max. intensity values of the input pattern. If not given, it is set to the pattern’s min./max intensity.

out_range

Min./max. intensity values of the rescaled pattern. If not given, it is set to dtype_out min./max according to skimage.util.dtype.dtype_range.

dtype_out

Data type of the rescaled pattern. If not given, it is set to the same data type as the input pattern.

percentiles

Disregard intensities outside these percentiles. Calculated per pattern. Will overwrite in_range if given.

Returns:
rescaled_pattern

Rescaled pattern.
