Alpha-trimmed mean filter is an order-statistics filter summarized by this equation, f(x,y) = mn-a 9n(s,t) (s,t)esxY where is the trim parameter, which dictates the /2 lowest and /2 highest values to be deleted before averaging the remaining pixel values g (0) Apply a 3x3 alpha-trimmed mean filter (Em, n -3; a-4) on the image below, applying 1-pixel zero padding along the borders. Draw the output filtered image (ensure final values are rounded to the nearest integer) 13 marks] Input image: 180 210 112 8 177 97 70 101 195 (ii) What is the value of for a 3x3 alpha-trimmed mean filter to function like a [1 mark] median filter?
