Selected Past Work

1D-2D color code decoding from printed images

Client: Color Code Technologies, Japan

1 Dimensional Color Code                      2 Dimensional Color Code

       


Prizatech was responsible for developing the libraries & applications for decoding such codes on various mobile operating systems such as Symbian, iOS & Android.

The major challenges in this project were:

- Detection of the 1D & 2D code region

- Compensating for camera skew

- Color reproduction (using color quantization), under various lighting conditions and various paper colors & textures

- Performance (less than one sec for phones out in 2009)

- Robustness & high accuracy


Elliptical Augmented Reality Code Marker


       


Prizatech has invented the Elliptical Augmented Reality (EAR) code marker, and has developed fast & robust algorithms for detecting and tracking this marker.


It's circular design makes detection easier even when the code is skewed or seen through a poor camera.
It is aesthically appealing as the code can be placed on a light backgroud with a logo in the centre, as opposed to standard boring QR codes.

Color Correction & Image Enhancement for AR-enabled Pico Projectors

Secure Mobile Device




A secure mobile device attempts to authenticate a user based on whether his biometric information matches that on his smart card.

On the smart card is printed a QR code which contains this user authentication information.

Using this information, the device does face & fingerprint authentication.

This was implemented for an Android operating system. The application tracked the user's face in real time and continuously authenticated it, stopping once a certain similarity score was reached.
