The main idea is to develop iOS/Android app, with facial recognizion of users from social network in the real-time video stream. After successfull face recognizion user information should be shown as augmented reality.

Just like in the example: http://www.youtube.com/watch?v=tb0pMeg1UN0

Stages:
1. The development of the algorithm for the server side of the app. The algorithm should detect and recognize user faces in the real-time video stream.
Requirements:
1. Input data: a video stream or a series of images with required format.
2. Output data: 3d/2d coordinates of the user's face, the angle of the face rotation in the video stream or a picture, social network user id.
3. The algorithm should recognize faces under different rotations of the head with the 3 coordinate axes.
4. The algorithm should recognize faces under different facial expression
5. Algorithm should determine the number of people simultaneously

2. Developing social network web-site
3. Developing web-services for iOS / Android clients
4. Development iOS / Android client
