ROI Assisted Digital Signal Processing for Rolling Shutter Optical Camera Communications

摘要

In this paper we propose a novel region of interest (ROI) detection based digital signal processing scheme for optical camera communications (OCC): it provides significant improvement in recovering the source shape induced signal deformations in a rolling shutter optical camera communication (RS-OCC) system over a link of 100 cm. We propose also a novel approach to address the packet losses due to the RS-OCC bursty channel, which relies on repeated packet transmission. We show simulation results for two different packet repetition schemes and compared them with the link with no repetition in RS-OCC.
