Query: A Systematic Scheme for Measuring the Performance of the Display-Camera
  Channel   Display-camera communication has become a promising direction in both
computer vision and wireless communication communities. However, the
consistency of the channel measurement is an open issue since precise
calibration of the experimental setting has not been fully studied in the
literatures. This paper focuses on establishing a scheme for precise
calibration of the display-camera channel performance. To guarantee high
consistency of the experiment, we propose an accurate measurement scheme for
the geometric parameters, and identify some unstable channel factors, e.g.,
Moire effect, rolling shutter effect, blocking artifacts, inconsistency in
auto-focus, trembling and vibration. In the experiment, we first define the
consistency criteria according to the error-prone region in bit error rate
(BER) plots of the channel measurements. It is demonstrated that the
consistency of the experimental result can be improved by the proposed precise
calibration scheme.
