Performance enhancement of optical camera communication system using optical camera communication coding and region‐of‐interest detection

Performance Analysis of Optical Communication System using Different Channels

Strong atmospheric turbulence (disturbance due to rain, fog, haze etc.) is a major problem in optical communication system. In this paper, the performance analysis of an optical communication system with Free Space Optics (FSO), Optical Wireless Communication (OWC) and Single Mode Fiber (SMF) in weak atmospheric turbulence has been analysed. Data stream is transmitted at 20Gbps using different ...

Robust Camera Pan and Zoom Change Detection Using Optical Flow

Detection of camera motion is essential for automated video analysis. Changes in camera pan and zoom are two important events to be identified. This paper proposes optical flow based techniques to identify these events. The scheme detects pan change by finding the number of flow vectors that correspond to the dominant orientation. An orientation histogram has been proposed to quantify the direc...

Experimental Characterization of Close-Emitter Interference in an Optical Camera Communication System

Due to the massive insertion of embedded cameras in a wide variety of devices and the generalized use of LED lamps, Optical Camera Communication (OCC) has been proposed as a practical solution for future Internet of Things (IoT) and smart cities applications. Influence of mobility, weather conditions, solar radiation interference, and external light sources over Visible Light Communication (VLC...
