I have just received a number of Photo's from early 1900s, some of them are children and some I suspect are the same children in later life, My question is this, Can I compare the photo's using face recognition? if so how do I go about it?.
There is no direct function to do this. However, if you upload the photos to the site, you can use the face-recognition-based tagging functionality, to try and locate similar photos (http://www.myheritage.com/FP/tag-people.php). You can also try the fun look-alike meter at http://celebrity.myheritage.com/look-alike-meter.
