Try this (untested):
% Get list of all of the filenames in the list,
% regardless of whether they are selected or not.
ListOfImageNames = get(handles.lstImageList, 'string');
numberOfItems = length(ListOfImageNames);
% Get the index(es) of the entry they've selected.
Selected = get(handles.lstImageList, 'value');
% Get the index(es) of the entry they've NOT selected.
notSelected = find(~ismember(1:numberOfItems, Selected))

Hi,
you could do the following if I understood the question correclty:
allStrings = get(handles.listbox1, 'string');
selected = get(handles.listbox1, 'value');
% all indices:
allIndices = 1:length(allStrings);
% now subtract:
unselected = setdiff(allIndices, selected);
