Open source implementation of CVPR 2020 "Video to Events: Recycling Video Dataset for Event Cameras"

Video to Events: Recycling Video Datasets for Event Cameras

This repository contains code that implements video to events conversion as described in Gehrig et al. CVPR'20 and the used dataset. The paper can be found here

News

We now also release new python bindings for esim with GPU support. Details are here

Dataset

The synthetic N-Caltech101 dataset, as well as video sequences used for event conversion can be found here. For each sample of each class it contains events in the form class/image_%04d.npz and images in the form class/image_%05d/images/image_%05d.png, as well as the corresponding timestamps of the images in class/image_%04d/timestamps.txt.
