CamMark A Camcorder Copy Simulator
common benchmark for robust watermarking system for digital video.
Home
CamMark is an open source tool to simulate the effects of recording a video from a display. One of its applications is to support the development of any system that includes evaluations of re-captured video. It also serves as a common benchmark for robustness against camcorder copies, for example in the field of digital video watermarking.

August 26th, 2015 - Version 1.1 of CamMark available
The implementation of CamMark was extended by a fully realistic frame blending model and simulation. Simulated effects include not only source and capture frame rate differences, but also the display's refresh rate and player adjustments to sync to this rate (V-sync mechanisms), exposure time, and the simulation of rolling shutters (with adjustable sensor readout times).
Additionally, the simulation now includes pulse-width modulated LCD backlights. Pulse-width modulation is typically used to dim the brightness of LC-displays. In combination with the temporal sampling of a camera and especially rolling shutters, this is responsible for the typical flickering effect seen in many recordings.
