- 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.
- 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.
- 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.
- Low pass filter in spatial domain is smoothing filter. Explain it.
- Explain implementation of Laplacian operator in 2D space and in 2D spectrum. State an application of Laplacian.
