# scipy.ndimage.filters.laplace

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

  Calculate a multidimensional laplace filter using an estimation for the second derivative based on differences.

  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
