2. (5 points) Given the following Matlab code that filters impulse noise from an image.
1 %clear all existing variables
2 clear
3 %close all existing figures
4 close all
5 %clear command window
6 clc
7 %Load a demo image into Matlab 8 i = imread( ’ coins . png ’ ) ;
9
10 %Add salt and peper noise
11 i = imnoise ( i , ’ salt & pepper ’ ) ;
12
13 %Filter out the salt and pepper noise
14 j = medfilt2 ( i ,[5 5]) ;
15
16 %display results
17 subplot (121) ; imshow( i ) ; t i t l e ( ’ Noisy image ’ ) ;
18 subplot (122) ; imshow( j ) ; t i t l e ( ’ Filtered image ’ ) ;
19 print ( ’q2 . png ’ , ’−dpng ’ ) ;
Write your own median filter called mymedfilt2 that operates same as the built in Matlab medfilt2 function.
