Exercise 2: (1). Read the image blurry-moon.tif and sharpen it using the Laplacian kernel.

(2). Read the image blurry-moon.tif and sharpen it using unsharp masking. Use a Gaussian

lowpass kernel of your choice for the blurring step. Display your final result.

(3) Improve the sharpness of your result using highboost filtering. Display the final result.

Compare the results with (1) and (2).
