how to repair the error of read multiple images in one folder and proceed directly to the background removal stage and generate fractal dimension values from those images

%-Read Folder
clc;
clear all;
image_folder = 'F:\kuliah\semester6\TA2\Implemen';
filenames = dir (fullfile(image_folder, '*.jpg'));
total_images = numel(filenames);

for n = 1:total_images
    f = fullfile(image_folder, filenames(n) .name);
    our_images = f;
    figure (n)
    imshow(our_images)
end
%-Remove Background
citra= our_images ;
% figure, fig1=imshow(citra);
load mri
V = squeeze(citra);
citra3=montage(reshape(V,size(citra)),map,'Indices',3);
saveas(citra3,our_images);

% To search fractal dimension
citra4= our_images;
figure, fig1=imshow(citra4);
[n, r] = fboxcount(citra4,'slope');
    df = -diff(log(n))./diff(log(r));
    disp(['Df= ' num2str(mean(df(4:8)))]);

What are you trying to do with loading mri, and with montage? montage wants a variable full of images or image names. What are you doing with the squeeze and reshape?

[Frisda Sianipar]

we use loading mri to remove the background from the image. Meanwhile, montage, squezee and reshape are part of the code load mri

I'm sorry but that makes no sense at all. "mri.mat" is a demo file that ships with MATLAB and doesn't have anything at all to do with your code at all. The variables it loads are not used elsewhere in your code. And having them doesn't have anything at all to do with removing any background.

similarly, to say "montage, squezee and reshape are part of the code load mri" makes no sense at all. Yes they are part of your code but what is your intent with them? Then don't remove background and aren't involved with montaging the images.

If you can't figure out how to use montage(), then try imtile(), but first read the documentation about what kinds of arguments it wants.

so, can you help me to find code about emove background?
