We present a dataset of sign language (SL) of gestures peformed by different people representing animals recorded with a DVS sensor:

SL-ANIMALS-DVS

The SL-ANIMALS-DVS database consists of DVS recordings of humans performing sign language gestures of various animals as a continuous spike flow at very low latency. This is especially suited for sign language gestures which are usually made at very high speeds. The dataset has about 1100 samples of 58 subjects performing 19 sign language gestures in isolation at different scenarios, providing a challenging evaluation platform for this emerging technology.
