How to transform my image into an image with grids like the attached image.

Hello everyone I have an image (original image), I would like to transform as the image (desired image).

You have the data in hand or only image?

I only have images. Two images are given as an attachment.

img = imresize(rgb2gray(imread('ia.png')),[256 256]);
img(:,1:3:end) = 1; 
img(1:2:end,:) = 1; 
imshow(img)

I wrote this code to display the grids but it does not look like the desired image.

What do you mean when you say 'does not look like the desired image'? Do you want the output to be identical to the desired image you've uploaded, or just the general features such as binary colors and grid size?

I would like the output to be identical to the "desired image" I have uploaded.
