T. Serrano-Gotarredona and B. Linares-Barranco, "A 128x128 1.5% Contrast Sensitivity 0.9% FPN 3us Latency 4mW Asynchronous Frame-Free Dynamic Vision Sensor Using Transimpedance Amplifiers," IEEE J. Solid-State Circuits, vol.48, No. 3, pp. 827-838, March 2013 (available from: http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6407468)

while browsing poker cards in front of it very quickly.
Three recordings are available

cards_1.aedat
cards_2.aedat
cards_3.aedat

These recordings can be displayed using the jAER software (http://sourceforge.net/p/jaer/wiki/Home) with filters tmpdiff128, DVS128 or RetinaTeresa2.

Matlab scripts run1.m run2.m and run3.m extract from these 3 recordings a number of tracked symbols cropped into a 32x32 pixel window, as they cross the screen.

The resulting tracked and extracted symbols can also be directly downloaded from this repository.
There are 30 club symbols, 43 diamond symbols, 23 heart symbols, and 35 spade symbols. Total 131 tracked symbols. The suffix 'i' (for example, xspade29i.aedat) means the symbol appeared inverted on the card.
All resulting .aedat files can be viewed using the jAER software (http://sourceforge.net/p/jaer/wiki/Home) with filters tmpdiff128, DVS128 or RetinaTeresa2.
