Use the same image as in HW6: 
-
Generate and show four levels of multi-resolution. Use a Gaussian kernel of your choice.
-
Generate and show four levels of multi-scale. Use the same Gaussian kernel as above.
-
Generate Laplacian planes using a Laplacian kernel of your choice (can use Laplacian of Gaussian, or Laplacian).
-
Generate approximation to Laplacian using the difference of Gaussian planes from (1). Note, you need to do 'Expand' on images before taking the difference.
-
Generate approximation to Laplacian using the difference of Gaussian planes from (2)
Provide code (can use in-built functions as may be needed), comments (if any), and output images.
