Implementing an optical communication system
between two smartphones, using their display and camera.
The system is based on image processing algorithms for the detection
and decoding of the received data.
Project’sObjective
Features
Project successfully implemented and run in real timeonandroid phones
and tabletswith the following features
The input data is encoded into 2D color video barcode, while each frame
represent a fraction of the transferred data.
Secure communication due to the nature of visible light.
The transmitted barcode size is automatically adapted to the transmitter’s
screendimensions, for best performance
Fast corner detection algorithm
Perspective transformation estimation and correction improves capture from a
wider angle range.
ReedSolomonerror correction code improves transmission reliability
