scipy.ndimage.morphology.black_tophat¶
- scipy.ndimage.morphology.black_tophat(input, size=None, footprint=None, structure=None, output=None, mode='reflect', cval=0.0, origin=0)[source]¶
Multi-dimensional black tophat filter.
Parameters : input : array_like
Input.
size : tuple of ints
Shape of a flat and full structuring element used for the filter. Optional if footprint or structure is provided.
footprint : array of ints, optional
Positions of non-infinite elements of a flat structuring element used for the black tophat filter.
structure : array of ints, optional
Structuring element used for the filter. structure may be a non-flat structuring element.
output : array, optional
An array used for storing the output of the filter may be provided.
mode : {‘reflect’, ‘constant’, ‘nearest’, ‘mirror’, ‘wrap’}, optional
The mode parameter determines how the array borders are handled, where cval is the value when mode is equal to ‘constant’. Default is ‘reflect’
cval : scalar, optional
Value to fill past edges of input if mode is ‘constant’. Default is 0.0.
origin : scalar, optional
The origin parameter controls the placement of the filter. Default 0
Returns : black_tophat : ndarray
Result of the filter of input with structure.
