Please be more specific about how you are selecting objects and how you are deleting them.

@Walter: If I had to guess it was done via this - http://www.mathworks.com/matlabcentral/answers/42558#answer_52367

This is not something you can just undo. If you maintain a history of the shape and position of the blob's you delete, then you could re-populate them, but other wise what is done is done. There's no "ctrl+z" seeing as that function was just created for you.

You could possibly tweak the function provided by Sean so that it works on a copy of your original image so you could retrieve back the original in case you do not like the selection you deleted.

[Sean de Wolski]

He could have a second axes or subplot that has the original and have it be add back.

Hi,

If you're using linux the default shortcuts commands is configured like Emacs, however, you can configure that like Windows, see https://www.mathworks.com/matlabcentral/answers/263833-linux-hot-key-settings.
