2020 arXiv   pre-print
Instead of capturing images at a fixed rate, they measure per-pixel brightness changes asynchronously.  ...  Hence, event cameras have a large potential for robotics and computer vision in challenging scenarios for traditional cameras, such as high speed and high dynamic range.  ...  To overcome them, [106] proposes a data-driven method to learn the TS appearance of intensity-image corners.  ...

Flat panel display signal processing [article]

MA Michiel Klompenhouwer, G Gerard De Haan, RHJM Ralph Otten, GJ Hekstra
2006
With BFI, each frame is divided in two subframes: a 'data' and a 'black' subframe. In the data subframe, the LCD is driven to the desired level, while the black subframe is always driven to black.  ...  The application of a video processing based method for LCD motion blur reduction has some specific advantages over panel based methods.  ...  We have worked together on display related topics for many years, which was always a great pleasure.  ...
