Laplace Method (apertureSize)
NamespacesEmgu.CVImage<(Of <(TColor, TDepth>)>)Laplace(Int32)

www.emgu.com/wiki
Calculates Laplacian of the source image by summing second x- and y- derivatives calculated using Sobel operator: dst(x,y) = d2src/dx2 + d2src/dy2 Specifying aperture_size=1 gives the fastest variant that is equal to convolving the image with the following kernel: |0 1 0| |1 -4 1| |0 1 0|
