Enabling Online Robust Barcode-Based Visible Light Communication With Realtime Feedback

Enabling Low-power Duplex Visible Light Communication

The new generation of LED-based illuminating infrastructures has enabled a “dual-paradigm" where LEDs are used for both illumination and communication purposes. The ubiquity of lighting makes visible light communication (VLC) well suited for communication with mobile devices and sensor nodes in indoor environment. Existing research on VLC has primarily been focused on advancing the performance ...

Retro-VLC: Enabling Low-power Duplex Visible Light Communication

The new generation of LED-based illuminating infrastructures has enabled a “dual-paradigm" where LEDs are used for both illumination and communication purposes. The ubiquity of lighting makes visible light communication (VLC) well suited for communication with mobile devices and sensor nodes in indoor environment.

Robust Video-Based Barcode Recognition via Online Sequential Filtering

We consider the visual barcode recognition problem in a noisy video data setup. Unlike most existing single-frame recognizers that require considerable user effort to acquire clean, motionless and blur-free barcode signals, we eliminate such extra human efforts by proposing a robust video-based barcode recognition algorithm. We deal with a sequence of noisy blurred barcode image frames by posin...

Indoor Localization Based on Visible Light Communication

Visible Light Communication

The visible light communication (VLC) refers to the communication technology which utilizes the visible light source as a signal transmitter, the air as a transmission medium, and the appropriate photodiode as a signal receiving component. The visible light communication technology has a short history compared with other communication technology, for example, public old telephone service, Ether...
