Note: If boundary extension is needed, please pad the boundary with O's. Your functions should be general enough to accommodate any square filter with odd numbers of rows and columns. 3. I4 points] Implement a MedianFiltering function to perform a filtering operation, as explained in class, on the input image. The prototype of this function should be: function filteredlm Median Filtering(im, mask) where im is the original grayscale image and mask is the square filter with odd numbers of rows and columns. Make sure that your function shows appropriate error messages when the mask's dimension is not an odd number and the mask is not a square. Note: both input and output images of the Median iltering function should be an array with data type uint8You are not allowed to simply use the Matlab "medfilt2" or other built-in functions in your implementation. However, you can use the built-in sorting function to sort the values covered by the mask. Call this function to process the same noisy image Circuit.jpg using a standard 3x3 median filter and a standard 5x5 median filter, respectively. Display the original image and two processed images in Figure 3 with appropriate ti tles. Hint: you may use matlab built-in function median0 to compute the median of an array
