An Open Software Suite for Event-Based Video

While traditional video representations are organized around discrete image frames, event-based video is a new paradigm that forgoes image frames altogether. Rather, pixel samples are temporally asynchronous and independent of one another. Until now, researchers have lacked a cohesive software framework for exploring the representation, compression, and applications of event-based video. Rather, they have focused on applications for individual cameras and data types. The AD Delta ER software suite aims to fill this gap. This framework includes utilities for transcoding framed and multimodal event-based video sources to a common representation, rate control mechanisms, lossy compression, application support, and an interactive GUI for transcoding and playback. This paper describes these various components and makes the open-source software available at https://github.com/ac-freeman/adder-codec-rs.
