How can i remove the noises (white pixels) in the image?

Can i know how can i remove the white pixels (noises) from the image?

I've tried using the medfilter but the result I obtained is just a pure plain picture.

Thank you.

One typical and simple way to do this is to use imopen function. Here is an example.

% Reading your image
I = imread('123.JPG');
I = rgb2gray(I);
BW = imbinarize(I);

% Apply imopen function
se = strel('disk',3);
BW2 = imopen(BW, se);

% Show the result
imshowpair(BW,BW2,'montage')
