How to select a folder at runtime?
显示 更早的评论
I have five folder. Each folder contains nearly 30 images. My programme is capable to read and execute all the images simultaneously from a specific folder by executing following code
srcFiles = dir('F:\Input_image\*.jpg');
for i = 1 : length(srcFiles)
filename = strcat('F:\Input_image\',srcFiles(i).name);
I{i} = imread(filename);
end
Each time when I execute all the folder I have to change the path, manually. Is it possible to change the path by executing the programme.

Try this:
% Have user browse for a file, from a specified "starting folder."
% For convenience in browsing, set a starting folder from which to browse.
startingFolder = 'C:\Program Files\MATLAB';
if ~exist(startingFolder, 'dir')
% If that folder doesn't exist, just start in the current folder.
startingFolder = pwd;
end
% Get the name of the folder that the user wants to use.
folder = uigetdir(startingFolder, 'Select a folder');
if folder == 0
% User clicked the Cancel button.
return;
end
filePattern = fullfile(folder, '*.jpg')
jpegFiles = dir(filePattern);
for k = 1:length(jpegFiles)
baseFileName = jpegFiles(k).name;
fullFileName = fullfile(folder, baseFileName);
fprintf(1, 'Now reading %s\n', fullFileName);
% Read in image and display it.
imageArray = imread(fullFileName);
imshow(imageArray); % Display image.
drawnow; % Force display to update immediately.
end
