digital imaging processing course
1. In most operations that require downsampling an image, the process will include a step to compute a smoothed version of the image before reducing the number of samples. Explain why such step is necessary? Elaborate on the advantages of using a gaussian smoothing filter in contrast to other averaging filters.
2. You were asked to inspect a problem with an imaging system used in your company. During testing, you found that the system produces images as the one shown at the bottom of Fig. 1 when taking images of objects that originally look like the image at the top. Can you identify at least one of the problems with this imaging system?
