Optical Lensless-Camera Communications Aided by Neural Network
Applied Sciences, 2019 Currently, the optical components of a camera embedded in the device constrain its overall thickness. Moreover, if the camera is strongly shaken, the lens and sensor may be misaligned, resulting in a defocusing effect.

A Simplified Model for the Rolling Shutter Based Camera in Optical Camera Communications [PDF]
, 2019 A simplified model of the camera for optical camera communications (OCC) based on the rolling shutter effect is proposed and experimentally verified. In OCC, the key parameters are the exposure time, which is proportional to the DC gain and inversely ...
