How to add image in MATLAB GUI?
-
I want to switch back and forth between two images, like blinking: 1 second for the first image and one second for second image.

Answer:
I'm not totally sure of what you want to do (specifically what type of images you are trying to display), but here's some sample code that may do what you want: image1 = imread('cameraman.tif'); % Load a test image image2 = imread('circles.png'); % Load another test image hAxes = gca; % Get a handle to the current axes for iLoop = 1:5, % Loop five times imshow(image1,'Parent',hAxes); pause(1); imshow(image2,'Parent',hAxes); pause(1); end I used the general function http://www.mathworks.com/access/helpdesk/help/toolbox/images/imshow.html, but this sometimes changes other properties of the figure/axes and that may not be to your liking (since you mention adding this to an existing GUI). You may want to use the http://www.mathworks.com/access/helpdesk/help/techdoc/ref/image.html function instead. Also, instead of the for loop you could use a while loop that stops switching images when a condition is met (such as a button press).

How are your images stored in Matlab? As a matlab movie or a 3 or 4 dimensional matrix depending on if the images are color or grayscale. Also, if you have the image processing toolbox, implay and immovie. Another option assuming that your images are in a mxnx3xk (rgb color) or a mxnxk (gray scale) matrix. Then the following should work. Assuming the following Img - matrix storing image data either with dimensions mxnx3xk or mxnxk handles.imageAxes - handle for the axis you want to display the image (set the tag of the axis to imageAxes in GUIDE) Now you can loop through Img for i=1:k % display the i^th image use `Img(:,:,i)` for a gray scale stack image(Img(:,:,:,i),'parent',handles.imageAxes); pause(1) % pause one second end that's it.
