I have a `grayscale` image which I have converted to `binary`. But, when I `imwrite` it, I don't get a `binary` image. That is, an image with two values (i.e; 0,1), why is that?
Thanks.

Hi Med,
I understand that you are facing issues while trying to save a binarized image.
Unfortunately, I am not able to reproduce the issue on my end. Please try the below code snippet to see if it resolves the issue:
I = imread('image.png');
BW = imbinarize(I); % imbinarize generates a matrix with values 0 and 1 as per the Otsu threshold for your image
imwrite(BW, "BinaryImage.png"); % saves the binary image in the cwd
For more details, please refer to the following MathWorks documentation:
Hope this helps!
