Is there a way to extract the breast density of a mammography through Matlab code?

I hope is not too late an answer. Please take a look at the following tool:https://www.mathworks.com/matlabcentral/fileexchange/73360-breast-density-segmentation.
Beware that this implementation has been tested on digital mammograms (such as those from the INbreast dataset) and has not been tested on digitized mammograms (e.g. MIAS).

I have already found a software for breast density, but I will also like to try yours in order to compare the results.
I will let you know of the outcome.
Thank you very much!

% Load the mammogram image
img = imread('mammogram.jpg');
% Display the original image
figure;
imshow(img);
title('Original Mammogram Image');
% Convert the image to grayscale if it is not already
if size(img, 3) == 3
img = rgb2gray(img);
end
% Display the grayscale image
figure;
imshow(img);
title('Grayscale Mammogram Image');
% Apply median filter to reduce noise
filtered_img = medfilt2(img);
% Display the filtered image
figure;
imshow(filtered_img);
title('Filtered Mammogram Image');
% Binarize the image using a threshold
level = graythresh(filtered_img);
bw = imbinarize(filtered_img, level);
% Display the binary image
figure;
imshow(bw);
title('Binary Mammogram Image');
% Calculate the breast density
density = sum(bw(:)) / numel(bw) * 100;
% Display the breast density
fprintf('Breast density: %.2f%%\n', density);
% Classify the breast density
if density < 25
density_type = 'Fatty';
elseif density < 50
density_type = 'Scattered';
elseif density < 75
density_type = 'Heterogeneously dense';
else
density_type = 'Extremely dense';
end
fprintf('Breast density type: %s\n', density_type);
