# scipy.ndimage.filters.laplace

`scipy.ndimage.filters.``laplace`(input, output=None, mode='reflect', cval=0.0)

  N-dimensional Laplace filter based on approximate second derivatives.

  Parameters: | input : array_like Input array to filter. output : array, optional The output parameter passes an array in which to store the filter output. 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
