Problems solved by technology

Especially in some special application fields, such as video surveillance, medical imaging, etc., the storage requirements for image data are very large. Using traditional storage methods will generate large storage costs. For example, the 700TB data mentioned above, using traditional storage media, will require 14,000 Blu-ray discs with a capacity of 50GB, or 233 3TB hard drives, the latter weighing about 151 kg

Abstract

The invention relates to the technical field of information processing, in particular to an image storage method, an image reading method, an image storage device and an image reading device. The method comprises the following steps of carrying out wavelet transformation on an original image to obtain the wavelet transformation coefficients corresponding to multiple levels of sub-images; obtaininga target wavelet transformation coefficient corresponding to the sub-image with the level greater than or equal to a preset value; and encoding the target wavelet transformation coefficient into a DNA sequence according to a preset corresponding relationship between the DNA base sequence and the wavelet transformation coefficient. According to the importance of the levels and types of the sub-images to image reconstruction and the data volume of the sub-images, the target wavelet transformation coefficients corresponding to the sub-images meeting the requirements are selected for DNA coding,so that the coded data volume can be effectively compressed, the high-definition decoding can be guaranteed, and the efficient storage of the image data is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of information processing, and in particular to an image storage method, a reading method, a storage device and a reading device. Background technique [0002] With the development of life science technology, as well as the cross-development of life science and other science and technology, it is possible to use genetic material deoxyribonucleic acid (DNA) as a storage medium. The development of DNA synthesis and sequencing technology provides technical support for it to become a digital storage carrier. Digital information DNA storage refers to storing digital information in the base sequence of DNA. This technology uses a DNA synthesizer to artificially synthesize DNA for storage, and uses a DNA sequencer to read the stored information. As a storage medium, DNA has the following advantages compared with the existing magnetic tape or hard disk storage medium: First, the DNA body is extremely small...
