Technical description of the EPFL submission to the JPEG DNA CfP

TL;DR

This paper presents V-DNA, a versatile codec by EPFL that encodes images and JPEG streams into DNA sequences, combining JPEG XL for compression and a modified Raptor Code for DNA encoding, suitable for data transcoding.

Contribution

The paper introduces V-DNA, a novel DNA encoding codec that supports raw and compressed images, integrating JPEG XL and a modified Raptor Code for efficient DNA data storage.

Findings

V-DNA effectively encodes raw images and JPEG streams into DNA.

The codec achieves promising biochemical constraints compliance.

Objective metrics demonstrate competitive performance.

Abstract

This document provides a technical description of the codec proposed by EPFL to the JPEG DNA Call for Proposals. The codec we refer to as V-DNA for its versatility, enables the encoding of raw images and already compressed JPEG 1 bitstreams, but the underlying algorithm could be used to encode and transcode any kind of data. The codec is composed of two main modules: the image compression module, handled by the state-of-the-art JPEG XL codec, and the DNA encoding module, implemented using a modified Raptor Code implementation following the RU10 (Raptor Unsystematic) description. The code for encoding and decoding, as well as the objective metrics results, plots and biochemical constraints analysis are available on ISO Documents system with document number WG1M101013-ICQ-EPFL submission to the JPEG DNA CfP.
