How to smooth the given image?

I want to make the image 1 as smooth as possible such that it looks like image 2. I was thinking to decrease the grid size but I don't know how to do that. Thanks in advance,

image 1 image 2

You can use the imgaussfilt() function to smoothen the image

Example code:

I = imread('index.jpeg');

figure();

imshow(I);

I = imgaussfilt(I,2);

figure();

imshow(I);

Before Blur is smoothening is applied

After smoothening is applied

Use imnoise() to add noise to it, then use imfilter() to blur it.
