Median filter and Gaussian filter Assessment

Target image (original image assessment section):

Figure 1

Q1. Figure 1 is a MRI image has salt and pepper noise. Try median filter and Gaussian filter to filter out these noises. Discuss the effect of window size to the filter effect. Try to enhance the image to have a clearer view of brain.

Do you have any more filter to try except for Median and Gaussian filter?

Use at least two kinds of filters to do the edge detection. Discuss the advantages and disadvantages.

Figure 2

Q2. Figure 2 is the

Binary image of bacteria

? Try the region labelling and tell the number of bacteria in the image? Is this value true and why? How will you improve the situation? (Tip: using

dilation and erosion

). Re-labelling the image and discuss the difference.
