N-WLASL dataset is a synthetic event-based dataset comprising 21,093 samples across 2,000 glosses. The dataset was collected using an event camera to shoot toward an LCD monitor. The monitor plays video frames from WLASL, the largest public word-level American Sign Language dataset. We use the event camera DAVIS346 with a resolution of 346x260 to record the display. The video resolution of WLASL is 256x256 and the frame rate is 25Hz. To ensure accurate recording of the display, we have implemented three video pre-processing procedures using the python-opencv and dv packages in Python.
