Image Segmentation and Saving image

hello I'm a final year student using Matlab for image segmentation but I have a problem. How do I save multiple pictures automatically? Please help, thank you

image_folder = 'C:\Users\ADMIN\Matlab\Implementasi';

outfolder = 'C:\Users\ADMIN\Matlab\Implementasi\output';

if ~isdir(outfolder); mkdir(outfolder); end

load mri %I presume it has the variable map in it

files = dir(fullfile(image_folder, '*.jpg'));

% filenames = fullfile({fileinfo.folder}, {fileinfo.name});

% total_images = numel(filenames);

for iFiles = 1:numel(files)

thisfilename = fullfile(files(iFiles).folder,files(iFiles).name);

% for n = 1 : total_images

% thisfile = filenames{n};

[~, basename, ext] = fileparts(image_folder);

citra = imread(thisfilename);

V = squeeze(citra);

fprintf('processing %s\n', basename);

citra3 = montage(reshape(V,size(citra)), map, 'Indices', 3);

outfile = fullfile(outfolder, sprintf(['%s-coba-%03d.%s',basename,ext]));

saveas(citra3, outfile);

end

I have try this from the link which you give but it doesn't create a new folder and save the image to the new folder. Can you tell me why it doesn't work?

Images=dir('C:\input_path\folder_name\*.png'); % Create Folder

outDirectory='C:\out_put_path\out_folder_name\'; % Save Folder

for i=1:length(Images)

ImgName=strcat('C:\C:\input_path\folder_name\',Images(i).name);

In_image=imread(ImgName);

%% Do operation

%Save the image, say result_image

imwrite(result_image,strcat(outDirectory,Images(i).name));

end

[KALYAN ACHARJYA]

Try with this way: Set the Current working directory in Input Folder Path

path_directory='...'; % 'Input Images Folder name Only'
original_files=dir([path_directory '/*.jpg']); % Folder Images in the same Directory
........................................^ Modify as per input images format
folder='output_folder'; % Create Folder to Save Results
for k=1:length(original_files)
      filename=[path_directory '/' original_files(k).name];
      image_orginal=imread(filename);
      %%.Do Operation
      result=
      fullFileName = fullfile(folder, original_files(k).name);
      imwrite(result,fullFileName);
end

I'm sorry but there is error missing extra character in the code namely "result =". Can you tell me what is this mean?

[KALYAN ACHARJYA]

Oh, this is partial code, the result, I represent the output image, which you want to save. Consider your output image there and change the result variable name accordingly.

[Rosida Octavia Sitorua]

I want to read all the images in the folder, then segmented and stored in a new folder. But when the segmentation process is only one image running, everybody help me? Thank you very much.

image_folder = 'C:\Users\ADMIN\Matlab\Implementasi';

outfolder = 'C:\Users\ADMIN\Matlab\Implementasi\cobaku';

if ~isdir(outfolder); mkdir(outfolder); end

figure, fig1=imshow(citra);

files = dir(fullfile(image_folder, '*.jpg'))

%change to grayscale

grayimg = rgb2gray(citra);

figure, fig2=imshow(grayimg);

%change to green channel

green_channel = citra(:,:,2);

figure, fig3=imshow(green_channel);

%change to CLAHE (Contrast Limited Adaptive Histogram Equalization)

CLAHE = adapthisteq(green_channel);

figure, fig4=imshow(CLAHE);

ER = edge(CLAHE, 'canny');

EG = edge(CLAHE, 'canny');

EB = edge(CLAHE, 'canny');

anyedge = ER | EG | EB;

figure, fig5=imshow(anyedge)

size(fig5)

load mri %I presume it has the variable map in it

for iFiles = 1:numel(files)

thisfilename = fullfile(files(iFiles).folder,files(iFiles).name);

[~, basename, ext] = fileparts(image_folder);

citra = imread(thisfilename);

V = squeeze(citra);

fprintf('processing %s\n', basename);

fig = figure;

citra3 = montage(reshape(V,size(citra)), map, 'Indices', 3);

outfile = fullfile(outfolder, sprintf('%s-coba-%03d.jpg', basename, iFiles));

saveas(citra3, outfile);

end
