Q10. The following functions can be used to perform 3x3 median filtering of an image on the given 8-neighborhood of a pixel. Modify these codes so that the image is filtered using mean filter on the given 4-neighborhood of the pixel. 1 1 1 0 1 0 111 1 1 1 1 1 1 0 1 0 8- neighborhood 4-neighborhood def morphological(im, operator=np.min. ox=5, ny=5). newlm = Dr.zeros(im.shape) for x in range(im shape[0]): for y in range(im shape[1]): bist = neighbours(im, x, y, ox, ny) newlm[xx] = operator(alst) return newlm I det neighboursin, x, y, dx=1, ny=1); return im[max(x-nx, 0): min(x+nx+1, im shape[0]), max(y-ny.
