Recording Scene and Equipment

All datasets are recorded in the actual scenes, the recording scenarios are as shown.

The characteristics of the three datasets are summarized in the following Table, and they are described in detail below.

How to Get Datasets

We upload all the datasets to the cloud server. The user can click to download the datasets.

• Pedestrian Detection Dataset download

• Action Recognition Dataset download

• Fall Detection Dataset download

A large part of pedestrian detection raw data are converted to 4670 frame images through SAE encoding method with frame interval of 20ms. In our experiment, all these images have been labelled via annotation tool -labelImg.

Ways of Encoding

Conventional methods cannot process event data directly. Thus, we employ three encoding approaches here as Frequency, SAE(Surface of Active Events) and LIF(Leaky Integrate-and-Fire) to process continuous DVS event stream into a sequence of frame images, in order to fit for conventional deep learning algorithms. We provide our codes (in Python) respect to three encoding approaches shown in folders.

How to use the three codes of encoding

We provided a toy dataset file toy.aedat to verify our code for encoding. You can download this file, put it in your destination folder.

We provides basic tutorials about the usage of three encoding codes.

If you want to use the code of snn.py,you can enter the following command.

python snn.py /path/to/aedat/file

If you want to use SAE and Frequency you can replace snn with sae or frequency.
