ImageTColor, TDepthLaplace Method
http://www.emgu.com
Calculates Laplacian of the source image by summing second x- and y- derivatives calculated using Sobel operator. 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|
