DNA-CTMF: Reconstruct high quality image from lossy DNA storage via Pixel-Base codebook and median filter.

ABSTRACT: Limited by uncertain base errors in DNA storage, additional correction measures may introduce redundancy or even expand errors, resulting in poor reconstructed image. DNA-CTMF is proposed to reconstruct high quality images at high errors and indels. Firstly, Pixel-Base codebook and chaotic system ensure DNA sequences meet biological constraints. Then, codebook adjusts offset base-groups affected by indels to their original position. Finally, median filter removes salt-and-pepper noise caused by base errors. Simulated experiments show reconstructed images by DNA-CTMF exhibit high quality with minimal variation at different error compositions. Even at 5 % error rate and indels accounting for 2/3, DNA-CTMF reconstruct high quality images with PSNR approximately 23 and MS-SSIM exceeding 0.9. T
