I wanted to diaplay all images in a folder one by one on the same axes using Matlab GUI. My below code is displaying only first image in the folder? kndly give the solution

handles.output = hObject;

filelist=dir(fullfile('E:\desktop\MATLAB\img-seg\CNN\ias1\*.jpg'));

handles.filelist = filelist;

handles.frameindex = 1;

% Update handles structure

guidata(hObject, handles);

axes(handles.axes1);

filelist = handles.filelist;

frameindex = handles.frameindex;

myfolder='E:\desktop\MATLAB\img-seg\CNN\ias1';

currentframefile = filelist(frameindex).name;

handles.frameindex = frameindex+1;

ff=fullfile(myfolder,currentframefile);

I=imread(ff);

imshow(I);

guidata(hObject, handles);

Isn't this a duplicate of your other question where I referred you to the FAQ?

Thank you sir. Now its displaying all images in a single axes. but transition from one image to another is too fast. i want a pause between flipping of two frames. kindly tell what modifications i have to do in the following below code.

% Specify the folder where the files live.

myFolder = 'E:\desktop\MATLAB\img-seg\CNN\ias1\*.jpg';

% Check to make sure that folder actually exists. Warn user if it doesn't.

if ~isfolder(myFolder)

errorMessage = sprintf('Error: The following folder does not exist:\n%s\nPlease specify a new folder.', myFolder);

uiwait(warndlg(errorMessage));

myFolder = uigetdir(); % Ask for a new one.

if myFolder == 0

% User clicked Cancel

return;

end

end

% Get a list of all files in the folder with the desired file name pattern.

filePattern = fullfile(myFolder, '*.jpg'); % Change to whatever pattern you need.

theFiles = dir(filePattern);

for k = 1 : length(theFiles)

baseFileName = theFiles(k).name;

fullFileName = fullfile(theFiles(k).folder, baseFileName);

fprintf(1, 'Now reading %s\n', fullFileName);

% Now do whatever you want with this file name,

% such as reading it in as an image array with imread()

imageArray = imread(fullFileName);

imshow(imageArray); % Display image.

drawnow; % Force display to update immediately.

end

Before the end of the loop, after the drawnow, call pause(0.5) where the number is the number of seconds you want it to wait.

Okay. Thank you Sir
