Generally it can be done using LaplacianImageFilter, which will compute the Laplacian by summing over the second order difference in the x,y and z directions, using the default kernel in the laplacian operator. </div><div><br></div><div>But, I need to take into account also the variation along xy, yz etc and other diagonal directions. So, I figured I could change the default kernel in order to do this, but I cannot find a way to modify the kernel. </div><div><br></div><div>Any help will be highly appreciated</div><div>Thanks</div><div>Vikash</div></div></body></html>
