You are talking about Photo Mixes, which can be created by Morpheus Photo Mixer or Morpheus Photo Animation Suite.
Assuming you are subtle about what you mix and the two pictures you are mixing are fairly similar, then no, there is no way you could tell that the resulting picture was mixed. With absolutely any software that does something similar to this, it would always be possible to tell that the mix is manufactured if you choose to exaggerate the results too much or mix drastically different pictures.
