imM=im>80;
axes(handles.axes2)
imshow(imM);
title('Threshold Image');

Somehow you got rid of the required input arguments, which should be hObject, eventdata, handles
To fix:
function pushbutton2_Callback(hObject, eventdata, handles)

Of course. I knew you'd find that out. All variables are local unless you make them not local. So where is im defined in that function? It's not. Where did you define it?
See the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F for ways you can share variables between functions.

I used global im but it has no image output.

Global just declares that the variable is able to be "seen" by that function. It doesn't really have "an output" per se, it just makes the variable able to be seen. Of course if you've never assigned that variable ever before in any function, then it will be undefined. Show me the function where you first assigned a value to im.
