Image files used in our experiment. (a,b) show the raw images which were compressed, encoded and synthesized into DNA blocks. The Citizen Kane poster¹⁹ (photographed by Kahle, A., date of access: 17/11/2016) RKO Radio Pictures, not copyrighted per claim of Wikipedia repository) and Smiley Face emoji were of size 9,592 and 130.2 bytes, and had dimensions of 88 × 109 and 56 × 56 pixels, respectively. (c,d) show the recovered images after sequencing of the DNA blocks and the post-processing phase without homopolymer error correction. Despite having only two errors in the Citizen Kane file, we were not able to recover any detail in the image. On the other hand, one error in the Smiley Face emoji did not cause any visible distortion. (e,f) show the image files obtained after homopolymer error correction, leading to an error-free reconstruction of the original file.
