Put the code into a function. Set the Callback of the uicontrol to call the function.

function MyProject_push1_Callback(hObject, event, handles)
   my_steganography_function();

We import the image in axes and we have edit text box for the information. The text would be hidden inside the image. We would like the button to execute the code for hiding the text inside the image.
