i think it is easier for you to use imagedatastore.
use :
images_left = imageDatastore('left_view_folder');
images_right = imageDatastore('right_view_folder');
where left_view_folder and right_view_folder are name of two folder. (you should run the code in folder contain these to folder otherwise put while path.)
then assuming you have a sequence for selection as you mentioned in comment: (for example)
left_views = [1, 1, 1, 1];
right_views = [1, 2, 3, 4];
so just do this:
for i=1:numel(left_view)
disparityMap{i} = map(readimage(images_left,left_views(i)) , readimage(images_right,right_views(i)));
end
readimage is a function wich get imageDatastore and index of image and return the image.
the above code is equal to :
for i=1:numel(left_view)
left_image = readimage(images_left,left_views(i));
right_image = readimage(images_right,right_view(i));
disparityMap{i} = map(left_image,right_image);
end
