Since convolution is commutative with respect to differentiation, the resulting wavelet
transform is the Laplacian of a Gaussian smoothed function. Thus, its zeroes correspond to the inflection points of the original function (Canny 1986). The contours of
zero crossing indicate the edges in the pattern of the input function. The detailed procedure of wavelet analysis is discussed in the following section.
