Exploiting the Rolling Shutter Read-Out Time for ENF-Based Camera Identification
Applied Sciences, 2023 The electric network frequency (ENF) is a signal that varies over time and represents the frequency of the energy supplied by a mains power system. It continually varies around a nominal value of 50/60 Hz as a result of fluctuations over time in the ...

Dynamical models for position measurement with global shutter and rolling shutter cameras [PDF]
2009 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2009 Vision can be used as a sensor for measuring the position of a visual marker. When the displacement of the marker over the camera exposure time is significant, the obtained position measurement is an image of the trajectory over the exposure time. This paper deals with dynamical models providing a prediction of the measurement from the continuous-time ...
