How to save image from one folder to another?

Hi,

How are you all? I want to read an image from a folder using matlab. Then I want to save the image to another folder of same directory? Is it possible? Please let me know.

Construct the filename with fullfile(), then call imwrite(). See the FAQ:

%read image test.jpg
tt= imshow('C:\Users\admin\Desktop\test.jpg') ;
%save your image other  location with any name save desktop or any folder also
saveas(tt,'C:\Users\admin\Desktop\testimagesave.jpg') ;

Try this:

% Demo by Image Analyst to read in a folder of JPG images and 
% copy them to a different folder in PNG format.
clc;    % Clear the command window.
fprintf('Beginning to run %s.m ...\n', mfilename);
close all;  % Close all figures (except those of imtool.)
clearvars;
workspace;  % Make sure the workspace panel is showing.
format short g;
format compact;
fontSize = 14;

% Specify the folder where the files live.
inputFolder = pwd; % 'C:\Users\yourUserName\Documents\My Pictures';
% Check to make sure that folder actually exists.  Warn user if it doesn't.
if ~isfolder(inputFolder)
	errorMessage = sprintf('Error: The following folder does not exist:\n%s\nPlease specify a new folder.', inputFolder);
	uiwait(warndlg(errorMessage));
	inputFolder = uigetdir(); % Ask for a new one.
	if inputFolder == 0
		% User clicked Cancel
		return;
	end
end
% Specify the output folder.
outputFolder = fullfile(inputFolder, 'PNG Files');
if ~isfolder(outputFolder)
	mkdir(outputFolder);
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(inputFolder, '*.jpg'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
for k = 1 : length(theFiles)
	baseFileName = theFiles(k).name;
	fullInputFileName = fullfile(theFiles(k).folder, baseFileName);
	fprintf('Now reading %s\n', fullInputFileName);
	% Now do whatever you want with this file name,
	% such as reading it in as an image array with imread()
	imageArray = imread(fullInputFileName);
	imshow(imageArray);  % Display image.
	caption = sprintf('File #%d of %d : "%s"', k, length(theFiles), baseFileName);
	title(caption, 'FontSize', fontSize, 'Interpreter', 'none');
	drawnow; % Force display to update immediately.
	% Create the output file name.  Change extension to .PNG.
	[~, baseFileNameNoExt, ext] = fileparts(baseFileName);
	fullOutputFilename = fullfile(outputFolder, [baseFileNameNoExt, '.PNG']);
	copyfile(fullInputFileName, fullOutputFilename);
end
message = sprintf('Done copying %d files.', length(theFiles));
uiwait(helpdlg(message));
fprintf('Done running %s.m\n', mfilename);
