(5) Add a white Gaussian noise to a blurred image g(x,y) that
has Gausssian mask applied, using “imnoise”. Show the noisy blurred
image. Apply a direct inverse filter to the noisy blurred image.
Show the restored image. Does it work? Why or why not? Calculate
the K value from the SNR of the image. Apply a Wiener filter to the
noisy blurred image with this K value. Show the restored image.
Make the K value 100 times bigger or 100 times smaller than the K
value calculated in . Discuss how the restored image quality is
affected by the K value?
