I knew this had to do with mapping faces to people, but what I had wrongly assumed was the simplicity. It took me less than a couple of hours to map about 2500 faces. I thought of sharing the accuracy of the tool &amp; conditions that baffled it.<\/p>\n<p style=\"text-align: justify;\">Unlike Orkut, where you have to mark faces yourself, Picasa automatically extracts faces. It took less than 5 minutes to extract some 5500 faces from about 3800 pictures. Another differentiator in the approach is that instead of mapping many faces on a photo (like Facebook, Flickr, etc), faces from many photos are brought together to be mapped to a person. This is what really saves time &amp; effort and retains interest. Statistically speaking, atleast 60% of all my photos (about 1800 Nos) feature one from my family of four. So in the ideal case, I will finish mapping 1800 photos in 4 clicks instead of 3600 clicks (assuming 2 faces per photo). That makes Google what it is: not just an applications company, but a technology company.<\/p>\n<p style=\"text-align: justify;\">I don&#8217;t know if people tagged by me will be suggested a priori to others in their photos.<\/p>\n<p style=\"text-align: justify;\">The tool started off with my photos, possible because the count was the highest. I showed me about 12 full sets (x16) of my pictures. A couple of photos in the first set were quite old &#8211; about 12 years back. Soon, it started suggesting my name for all my photos.<\/p>\n<p style=\"text-align: justify;\"><a href=\"http:\/\/prasadgupte.files.wordpress.com\/2010\/01\/pit_accurate_prasad_0.png\"><img loading=\"lazy\" decoding=\"async\" class=\"  aligncenter\" title=\"Started suggesting my name after a couple of sets\" src=\"http:\/\/prasadgupte.files.wordpress.com\/2010\/01\/pit_accurate_prasad_0.png\" alt=\"Started suggesting my name after a couple of sets\" width=\"522\" height=\"400\" \/><\/a><\/p>\n<p style=\"text-align: justify;\"><!--more-->The next set had pictures about 17 years old, from my thread ceremony; my head was bald then (like now).<\/p>\n<p style=\"text-align: justify;\"><a href=\"http:\/\/prasadgupte.files.wordpress.com\/2010\/01\/pit_accurate_prasad_2.png\"><img loading=\"lazy\" decoding=\"async\" class=\"  aligncenter\" title=\"Identified me in photos as old as 1993\" src=\"http:\/\/prasadgupte.files.wordpress.com\/2010\/01\/pit_accurate_prasad_2.png\" alt=\"Identified me in photos as old as 1993\" width=\"455\" height=\"201\" \/><\/a><\/p>\n<p style=\"text-align: justify;\">This was the best: it could make me out in a black &amp; white bald photo, and when I had a mustache, and a beard &amp; a french beard.
