How to use 'median filter and gaussian filter' in matlab ?

image_folder ='E:\Resize Image' 
filenames = dir (fullfile(image_folder,'*.jpeg'))
total_images = numel(filenames);
results=[];
for n= 1:total_images;
   f= fullfile(image_folder, filenames(n).name);
   disp(f);
   our_images= imread (f); 
   
   % CONTRAST STRECHING
   s = imadjust (our_images,stretchlim(our_images,[0.01 0.99]),[]); %menentukan nilai maksimum dan minimum untuk peregangan

   % FILTERING
   noise = imnoise (s,'gaussian',0.05);
   denoise = medfilt2(noise);denoise1 = imgausstfilt (noise, 2) ;

Please help, here I am using Matlab version R2018a.

error in

Undefined function 'imgausstfilt' for input arguments of type 'uint8'.

Try imgaussfilt instead of imgausstfilt (note the extra t)

denoise1 = imgaussfilt(randn(100),2); % works

denoise1 = imgausstfilt(randn(100),2); % error

Unrecognized function or variable 'imgausstfilt'.

What's mean '100' in skrip denoise1 ?

[Voss]

I generated a random array to show that the function works if you call it by its correct name, imgaussfilt.

Oh Oke, thankyou very much..
