projectdir = 'path/to/image/directory';
ext = '.png'; %adjust according to kind of images
dinfo = dir( fullfile( projectdir, "*"+ext) );
fullnames = fullfile({dinfo.folder}, {dinfo.name});
nfiles = length(fullnames);
ax = app.axes1; %place you want the image to be shown
h = image(ax, []); %create image object with empty content
for K = 1 : nfiles
thisfile = fullnames{K};
[thisimg, thismap] = imread(thisfile); %handles pseudocolor and rgb both
h.CData = thisimg; %update the existing image object with the new image
if ~isempty(thismap); colormap(ax, thismap); end %if needed, update colormap
pause(0.2);
end
The above code does not, however, account for true grayscale images. You would detect those as thismap being empty and ndims(thisimg) is 2 .
