• Discuss the purposes of image enhancement.
• Describe the applications of logical (Boolean) operations.
• What is a convolution mask in the spatial domain? Explain how it works.
• Discuss the benefits of using a variety of masks, including the median and Gaussian masks, for smoothing.
• What is a separable function? What is the advantage to separate two-dimensional masks into one-dimensional masks?
