  1. 1. Spatial Smooth Filter
  2. 2. Summary• Choose an image (showed in figure 1), and then add noise to the image. The noise must have the following characteristics: – 20% impulse noise (showed in figure 2). – Gaussian noise with mean = 0 and variance = 0.05 (showed in figure 3).• Simulate a horizontal script in the original image (showed in figure 4).• Display the resulting image in parts (1) and (2).• Smooth the noisy images using the most suitable filter. – Filter pepper & salt noisy image (Figure 2) using median filter (showed in figure 5). – Filter Gaussian noisy image (Figure 3) using average filter (showed in figure 6). – Filter Scratch noisy image (Figure 4) using vertical median filter (showed in figure 7).• Display the smoothed images
