remove backgroung from the image

This code is for image segmentation from removing background - green channel - clahe - canny. But in this code we still input images one by one And I want the code to immediately read all the images in one folder and save the output in another folder. Can you help me? Please, thankyou in advance

close all;  % Close all figures (except those of imtool.)
workspace;  % Make sure the workspace panel is showing.

% Get the name of the image the user wants to use.
baseFileName = 'image.jpg';
folder = pwd;

e = fullfile(folder, baseFileName);
% Check if file exists.
if ~exist(fullFileName, 'file')
	% The file doesn't exist -- didn't find it there in that folder.
	% Check the entire search path (other folders) for the file by stripping off the folder.
	fullFileNameOnSearchPath = baseFileName; % No path this time.
	if ~exist(fullFileNameOnSearchPath, 'file')
		% Still didn't find it.  Alert user.
		errorMessage = sprintf('Error: %s does not exist in the search path folders.', fullFileName);
		uiwait(warndlg(errorMessage));

save the output of segmentation sir

You can use sprintf() or compose() to generate filenames, and call save() passing in the file name and the name of the variable to save.
