The reason for this strange behaviour is that the dtype of x is int64, and the scikit-image laplace function calls img_as_float in order to do the computation in float numbers, but when casting the dtype it also divides the array by the maximum value of the origin dtype (here 2^63 - 1), hence the very small values. output: array or dtype, optional.
