ROI Assisted Digital Signal Processing for Rolling Shutter Optical Camera Communications
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 ...
