MATLAB: Segment all the images in the lisbox

Image Processing Toolboxlistboxsegmentationthresholdingwatershed

I've multiple image in the listbox, 2 axes and 2 push button that is the segmentation method.(threshold and watershed) How can I segment all the images in the listbox and the orignal image is display in one of the axes and the segmented image in another axes. when click on different image the segmented image will actually correspond to the original image. All help is appreciated.

projectdir = 'the/directory_that/the/images/are_in';
selected_image_idx = get(handles.listbox1, 'Value');
all_image_names = cellstr( get(handles.listbox1, 'String') );
selected_image_names = all_image_names(selected_image_idx);
num_selected = length(selected_image_names);
for K = 1 : num_selected
  this_name = selected_image_names{K};
  this_image_file = fullfile( projectdir, this_name );   %presuming the stored name includes the extension
  this_image = imread(this_image_file);
  imshow(handles.axes1, this_image);      %original image
  title(handles.axes1, ['Original image: ', this_name ];
  title(handles.axes2, 'Segmentation being computed');
  imshow(handles.axes2, nan(1,1,3));      %blank output while we compute segmentation
  drawnow();
  segmented_image = segment_one_image(this_image);
  imshow(handles.axes2, segmented_image);
  title(handles.axes2, ['Segmented image: ', this_name ];
  drawnow();
end
