16. Photo Tagger Analysis
Explanation: We’re looked at accuracy in depth above, and I would only reemphasize that a 3 doesn’t do justice to Face.com’s ability to make decent if not stellar lemonade out of some very low-res lemons. Analysis speed is very good; only MediaShow’s CUDA-based acceleration can beat it. On ease of use, I have to give Photo Tagger a 3 here because the app itself is very simple (too simple in some ways), but Face.com is saddled with the Facebook infrastructure, Java idiosyncracies, and other factors beyond its control, and there were many times when I found myself battling these, and it makes judging a total tagging time very difficult. I only gave Photo Tagger a 3 for feature depth and innovation because the app itself, from an end-user’s perspective, is much like every other face tagger. It just does one job.
Stepping back, though, and looking at Face.com’s young applications as part of a platform changes things. I can clearly see the direction Face.com wants to go with social media, and it’s very compelling—and scary. What does it mean when you can snap a photo of someone on the street and search to see if he or she is single? Or what if you say, “I want to find 10 available women within 20 miles of my house who look just like this.” (Be careful what you ask for.) Employers could scan for their traveling workers. Parents could use this to keep tabs on their teens. Love it or hate it, that’s serious innovation. Face.com’s platform, if it goes where I suspect it will, deserves a 5 for innovation.
Note that, like other face taggers, Photo Tagger is a learning system. As Face.com CEO Gil Hirsch told me, “Photo Tagger gets better as you and your friends use the app more. It leverages information already collected to better its grouping and recognition, so in effect the first 1 to 2 albums will see base-level performance. But our usage statistics show that with your average Facebook users (about 170 friends on average), you'll get much improved results as usage continues.”

1. let just say I have spend weekly time on a low end pc to get 33 GB photo with so many file. How do I save this tag when I am reinstall windows?
2. About the portabilty in no 1. Picasa has picasa.ini in every folder, but when it corrupt, the picasa.ini is not helpful recovering the weekly time spent.
3. Speed? Why there is no benchmark graph like usual?
4. Try gradiation photos or something similiar. It will see about the acuration.
5. I want to get the best speed, what is the most needed hardware. If Processor will I7 better than C2D? If GPU, will Geforce GTX 295 better than 9800?
I have private paint experience using picasa. I have taging many face in a week of Sempron 2800+ OC to 2 Ghz. When the face recognation is done, for what ever reason, my cpu is dead (dead power electricity). When the electricity power is up, my pc is on windows. The picasa is corrupt. My one week OC is for nothing. DAMN
I recently tagged all my photos with Picasa. I think i personally tagged more than the software did--the software is VERY cautious. It also repeatedly asked to tag posters, even paintings that were on my walls. Finally, it doesn't do well with babies--which is no surprise because they all look the same to me too :-)
Its cool, but im not sure the outcome was worth sitting there tagging hundreds of pictures of ex-girlfriends.
I am giving comment for testing.
Deadlockedworld--you don't have to tag everyone in every album in Picasa--just don't tag albums that have your exes in them. I definitely don't tag everyone in my photos--only those people that are important to me.
Adobe's Photoshop Elements 7 has the ability to detect faces but not automatically match them. It did make tagging much quicker. I could select 40 pictures from a party and tag the lot all at once.
However, I found that there were several pictures that it didn't catch. So, I ended up having to go through the whole bunch manually anyway to catch the stragglers. I found I spent as much time, if not more, making sure I got everything. So, I'm not sure that the "helpful tool" actually did much.
I am using iPhoto '09 and I found that the predictive tagging is getting less and less accurate as the database of tagged faces increases. Impression confirmed by one of my friends using the same app. For example, my wife is probably the most frequent face in my collection and the software has a hard time identifying her. On the other hand, I tagged the face of a friend I see rarely and I was welcomed with 4-5 good matches.
