2- Write a MatiLab program to read the moon.tf" image and do the following: a- Smooth the given image by applying a linear spatial fiter b- Experiment with applying three different linear spatial filters to enhance the original image and the blurred image of part (a). c- Add Gaussian noise to the original image and apply linear and nonlinear filters to eliminate or reduce the noise. 3 Write a MatiLab program to read the "cameraman" image and experiment with applying the Fourier transform and the following fiters: a- Low and high pass Ideal fiters b- Low and high pass Butterworth filters What is the smallest radius of a low-pass ideal fiter for which the face is still recognizable
