MATLAB: How to save the output image

imagessave as

citra=imread('ISIC_0024336.jpg');
figure, fig1=imshow(citra);
load mri
V = squeeze(citra);
citra3=montage(reshape(V,size(citra)),map,'Indices',3);
saveas(citra3,'ISIC_0024336coba.jpg');

Would you help me please, How to save the output image in Matlab automatically?

Best Answer

infile = 'ISIC_0024336.jpg';
citra=imread(infile);
figure, fig1=imshow(citra);
load mri
V = squeeze(citra);
citra3=montage(reshape(V,size(citra)),map,'Indices',3);
[folder, basename, ext] = fileparts(infile);
outfile = fullfile(folder, [basename 'coba' ext]);
saveas(citra3, outfile);

MATLAB: Open a series of images and save them in another folder

See http://www.mathworks.com/matlabcentral/answers/13205#answer_18099 to format your code.

See the FAQ to process a sequence of images: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

You need to have two folder variables, one for input, and one for output. And you need two base file names, one for input and one for output. Then use full file to create two filenames:

fullInputFileName = fullfile(inputFolder, baseInputFileName);
fullOutputFileName = fullfile(outputFolder, baseOutputFileName);

baseInputFileName would be files(k).name.

See full demo below:

% Copies all the files from one folder to another folder.
clc;    % Clear the command window.
workspace;  % Make sure the workspace panel is showing.
format compact;
% Define input and output folders.
% CHANGE THESE FOLDER NAMES!!!!!!
inputFolder = pwd;
outputFolder = uigetdir(pwd);
if strcmp(outputFolder, inputFolder)
  errorMessage = sprintf('Error: the output folder must be different than the input folder');
  uiwait(warndlg(errorMessage));
  return;
end
% Check to see that both folders exist.
if ~isdir(inputFolder)
  errorMessage = sprintf('Error: The following input folder does not exist:\n%s', inputFolder);
  uiwait(warndlg(errorMessage));
  return;
end
if ~isdir(outputFolder)
  errorMessage = sprintf('Error: The following output folder does not exist:\n%s', outputFolder);
  uiwait(warndlg(errorMessage));
  return;
end
% Get a list of files to copy.
filePattern = fullfile(inputFolder, '*.*'); % All files.
% filePattern = fullfile(inputFolder, '*.m'); % m-files.
fileNamesToTransfer = dir(filePattern);
numFiles = length(fileNamesToTransfer);
% Do the copying.
for k = 1 : numFiles
  % Get the base file name.
  baseFileName = fileNamesToTransfer(k).name;
  % Create the full input and output filenames.
  fullInputFileName = fullfile(inputFolder, baseFileName);
  fullOutputFileName = fullfile(outputFolder, baseFileName);
  fprintf(1, 'Now copying file #%d of %d: %s to %s\n', ...
    k, numFiles, fullInputFileName, fullOutputFileName);
  copyfile(fullInputFileName, fullOutputFileName);
end
msgbox('Done copy files!', 'modal');
