An embodiment may involve obtaining an image composed of color channels, wherein each of the color channels represents colors therein with n bits per pixel; quantizing each of the color channels to be represented by m bits per pixel; using a space-filling curve to convert each of the color channels as quantized into respective vectors; generating, for each of the respective vectors, a respective set of m arrays, wherein the m arrays for a particular vector of the respective vectors contain indices of where a fixed value selected from a range of 0 to m&#x2212;1 is found in the particular vector; applying, to each of the m arrays for each of the respective vectors, differential encoding and compression of the indices therein; mapping each of the m arrays for each of the respective vectors to blocks of nucleotides; synthesizing the blocks; and storing, in a DNA-based storage medium, the blocks.

DNA-based image storage and retrieval

Nick-based methods, devices, and systems for nick-based data storage in a deoxyribonucleic acid (DNA) sequence are disclosed. Digital information is encoded in a register of at least one copy of a double-stranded DNA sequence having a plurality of nickable positions. The data is translated into a sequence of values from a nick alphabet that is subsequently mapped to the plurality of nickable positions, and the DNA sequence is nicked according to the mapped values. Because the digital information is encoded as a series of nicked and non-nicked positions of a double-stranded DNA sequence, the nucleotide sequence of the DNA can be non-synthetic, or 'native' DNA.
