4. Apple iPhoto ‘09: Wrinkles in Faces
The idea here is that the more matches you confirm, the smarter iPhoto will get about finding additional matches. If it does, you hit Confirm Name again and keep going. This sort of expanding circle of matches works well if you have lots of photos of the person and if those photos are reasonably clear. But the truth is that Apple’s recognition engine, much like those of its competitors, is no miracle worker. In fact, I was surprised at how little time it took to exhaust the number of hits that came back. After cycling through my four test subjects, I had to admit that iPhoto’s recognition routines could produce a decent-sized batch of matches in only a minute, but after that first wave the drop-off is steep. (Moreover, as you do name matches on various people, you’ll see the same incorrect matches reappear, which doesn’t do your time efficiency any favors.) After all, check out this image where only one out of four faces is tagged. It doesn’t take long before you find yourself, as I did, saying, “I’ve topped out at a couple dozen matches when I know there are over a hundred instances in this collection.”
At this point, there’s no choice but to start auditing each photo in the collection. Pick the first image in the Event, click the Name button to see its face tags, and get busy. Thankfully, Apple uses an auto-fill routine to show you existing names in a pull-down menu as you start typing the face’s name. So usually all you have to do is click on the “unnamed” field, type a letter or two, select the name from the pull-down, hit Return, do the same on any other faces shown, three-finger swipe to the next image, and repeat the process.

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.
