  1. Consider that image is corrupted by salt and pepper noise. Suggest better method to remove salt and pepper noise from the image. Explain that method and write Matlab/Scilab code for the same.
  2. Consider that image is corrupted by Gaussian noise. Suggest suitable method to minimize Gaussian noise from the image. Explain that method and write Matlab/Scilab code for the same.
  3. Explain spatial filtering process. Write MATLAB code for convolution of 3×3 filter mask with image of size MxN. Write 3×3 mask for low pass filtering and high pass filtering.
  4. Low pass filter in spatial domain is smoothing filter. Explain it.
  5.  Explain implementation of  Laplacian operator in 2D space and in 2D spectrum. State an application of Laplacian.
