Write an image name to particular folder using imwrite

Dear users ..

i have been used an bottom in GUI to browse an image from computer .. but when i used imwrite, i can not write that image with its name.. so its not efficient to give name to that image each time .. is there any way to write image with its real name .. thanks

[fname path]=uigetfile('*.*');
if isequal(fname,0) | isequal(path,0)
warndlg('Please select an image from directory ..');
else
fname=strcat(path,fname);
Im2=imread(fname);
imwrite(Im2,'D:\imagefolder','jpeg');

[Suvetha Ravi]

Can you give me a code that how can I store the resized and grayscaled images in a separate folder in a drive?Hoping for a reply!

Suvetha, yes - I already gave the code to ahmed. It is below - just scroll down or click here. Take note how there are both destinationFolder and folder (which is the input image folder).

Important Note: do not use path as the variable name for the folder like ahmed mistakenly did.

Try this robust (but untested) code:

% Have user browse for a file, from a specified "starting folder."
% For convenience in browsing, set a starting folder from which to browse.
startingFolder = pwd;  % or 'C:\Program Files\MATLAB' or wherever...
if ~exist(startingFolder, 'dir')
  % If that folder doesn't exist, just start in the current folder.
  startingFolder = pwd;
end
% Get the name of the file that the user wants to use.
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uigetfile(defaultFileName, 'Select a file');
if baseFileName == 0
  % User clicked the Cancel button.
  return;
end
fullSourceFileName = fullfile(folder, baseFileName)
originalImage = imread(fullSourceFileName);

% Create destination filename
destinationFolder = 'D:\imagefolder';
if ~exist(destinationFolder, 'dir')
  mkdir(destinationFolder);
end
% Strip off extenstion from input file
[sourceFolder, baseFileNameNoExtenstion, ext] = fileparts(fullSourceFileName);
% Create jpeg filename.  Don't use jpeg format for image analysis!
outputBaseName = [baseFileNameNoExtenstion, '.JPG']
fullDestinationFileName = fullfile(destinationFolder, outputBaseName);
% Write the jpg file.  This will convert whatever format you started with to the hated jpg format.
imwrite(originalImage, fullDestinationFileName);

Do not be afraid. It's well commented - just study it a line at a time.

I edited it to make it even more robust - I added mkdir() to create the destination folder if it does not yet exist.

[Moucharaph SALAHOU]

please sir how about Writing many images name to particular folder using imwrite?

[Moucharaph SALAHOU]

[baseFileName, folder] = uigetfile(defaultFileName, 'Select a file',...
'MultiSelect', 'on');

this is my code how can I save all the slected images into a folder...thank you for hepling

[Walter Roberson]

if ~iscell(baseFileName); baseFileName = {baseFileName}; end  %user selected only one
filenames = fullfile(folder, baseFileName);

% Create destination filename
destinationFolder = 'D:\imagefolder';
if ~exist(destinationFolder, 'dir')
  mkdir(destinationFolder);
end

% start saving
for K = 1 : length(filenames)
    fullSourceFileName = filenames{K};
    originalImage = imread(fullSourceFileName);
    % Strip off extenstion from input file
    [sourceFolder, baseFileNameNoExtenstion, ext] = fileparts(fullSourceFileName);
    % Create jpeg filename.  Don't use jpeg format for image analysis!
    outputBaseName = [baseFileNameNoExtenstion, '.JPG']
    fullDestinationFileName = fullfile(destinationFolder, outputBaseName);
    % Write the jpg file.  This will convert whatever format you started with to the hated jpg format.
    imwrite(originalImage, fullDestinationFileName);
end

y = [1,1,1,1,1];

x = [2,2,2,2,2];

z = [2,2,2,2,2];

a = [3,3,3,3,3];

b = [4,4,4,4,4];

c = [5,5,5,5,5];

figure;

h(1)=plot(x,y);

figure;

h(2)=plot(x,z);

figure;

h(3)=plot(x,a);

figure;

h(4)=plot(x,b);

figure;

h(5)=plot(x,c);

for k=1:5

baseFileName = sprintf('figure_%d.png',k);

fullFileName = fullfile(cd,'image', baseFileName); % cd :-> for storing the image in current directory and image:-> is the folder % % name (First you creat the folder on that particular directory)

saveas(gcf,fullFileName);

end
