Abstract
This paper proposes a data detection technique for screen-to-camera (S2C) based on visible light communication (VLC) system. In this optical camera communication (OCC) based system, the data transmitted as an image utilizing the transmitter smartphone screen (Tx) to be captured and decoded by the receiver smartphone camera (Rx). The region-of-interest (ROI) extraction is carried out on the received image followed by grayscale conversion, edge detection, pixel grouping, Hough and projective transform. The proposed method is executed on the Android platform across varying link spans, tilt angles, and rotation conditions. The results indicate that the introduced data detection algorithm, improved the overall detection rate to ~98%.
