Polar Rose - Face Recognition Search Engine !

Is not it search engines the favorite tool for netizans now? Yes it is. But unfortunately the search is concentrated only on ‘text’. But the web is becoming visually oriented now a day. About 10 million new photos are uploaded on a daily basis. And the number seems to be doubling every 8-10 months! So on this visually oriented era we obviously need to search for photos. Nope its not the image search that by google and yahoo now offers. They have nothing to do with it. Coz the idea behind it still lays with the text based labels etc.

But we need another tool that could search the contents of the photos. The first of its kind is announced by ‘Polar rose’.

What polar rose does?

Polar Rose is a new search engine that will allow you to find anyone in any photo on any site. The Polar Rose ‘plug-in’(see the photo) helps to build a database of identified people on basis of user input.
Polar Rose starts by identifying the parts of an image that looks like a person. In the picture (left), there are five parts that are identified as people's faces. If a person's face is not in the database, the application asks if you know that person. If the Polar Rose database knows the face, or if it has any possible matches, the plug-in will display it on the picture, and ask for your agreement or other input. Polar Rose would allow the users to annote the photo with descriptive details.

The Technology

According to Polar Rose, it relies on a combination of its unique face recognition algorithms and the collective intelligence of our users.
Polar rose official website says -The face recognition technology used was originally developed by some ‘CTO Jan Erik Solem' (during his M.Sc and Ph.D).
And according to the Swedish company the tool could search for similar looking photo across the net-say faces. It analyses digital photos to locate faces, and then convert the data from 2D images to 3D models called faceprints. This faceprints can be compared with other faceprints to find the match. Since the face print is a 3D image the image of a face from different angles could not be a problem.

Interestingly look alikes could pose a problem the software!

Word meaning polar rose : 'In mathematics, a rose is a sinusoid plotted in polar coordinates'-says wiki

[Of cOurse sOme part of the matter is cOpy pasted :D]

Disclaimer (means of escaping if some wrong info is posted ):I just sat and read and these are my inferences, need not be 100% correct.

People using bsnl dataone will see 'ADSL' written on the modems, which stands for Asymmetric Digital Subscriber Line. This is the reason why we have great downloads speeds (its upto 2mbps, not 2 mbps, can b 128 kbps, 1 mbps anything), but our upload speeds are very very low. ADSL is transmitted thru copper wires, so thats why BSNL people din have to dig up roads to lay wires like the Ambani's did. The signal for our Internet transmission uses different frequencies compared to our normal voice calls. So we can make calls nd use net at the same time...if u think that is no big deal, that is cos u haven't used dial-up.
The signal does not travel long distances thru these lines, usually only till 5 kms, so thats why rural people don't get dataone. thats why sreedish dint get dataone until a few months back, wen the exchange near his house started giving connections.

Blue region shows transfer from BSNL(service provider) office to your house nd green region shows transfer from your house to BSNL office. So i assume that since the blue region (downstream) is bigger, we get higher download rate...nd since green region(upstream) is smaller,we get lower upload rates..
and the red area shows the one for our normal voice calls.
My modem says its ADSL ,so its maximum downstream rate is 8 Mbits/sec nd max upstream is 1Mbit/seconds

What not to forget :

• ADSL is Asymmetric not Asynchronous or Assymetric
• Downstream doesn't mean the stream is at lower frequencies, but it means 'download stream'
• When u say your connection speed is 2Mbps, its not 2 Mega Bytes per sec, but its 2 Mega bits per sec....and its the download speed nd not your upload speed..remember ASYMMETRIC.

• @dish : the modems that are kept in our houses are also called routers. And routers are just not the only things that costs 1.5lakhs, heard you talking about with tommy, thats why i mentioned it here

nd wer da hell is comic sans :(..hope you have been enlitened

Here goes........

Even though our syllabus maybe outdated crap and the supply meter aint readin 0, We are "supposed" to be students of computer science engineering and theres no harm in keepin ourselves updated with the so called "latest trends" in technology. This joint tech blog is an attempt to create a common place where WE can post watever intresting tech related info we come across in cyberspace(If u dont usually come across such info..i suggest u start luking;) ). Try avoiding copy pasting as much as possible and write ur personal opinions. Most importantly, this blog is NOT for the ubergeek, its for the whole class and it would be best to keep this in mind while writing an entry. So if at all ur reading this and want to contribute leave ur email id in the comments section and ill sent ya an invite. :)
