Abstract

The invention discloses a data coding method and device and a storage medium. The data coding method comprises the steps: a to-be-coded character string and a preset interval length are acquired, wherein the to-be-coded character string comprises multiple first preset characters and multiple second preset characters; a coefficient critical value is determined according to the maximum number that the second preset characters continuously appear in the to-be-coded character string; a coding coefficient not less than the coefficient critical value is selected from a preset coefficient list; a first coding interval corresponding to the first preset characters and a second coding interval corresponding to the second preset characters are determined according to the interval length and the coding coefficient; the to-be-coded character string is coded by means of the interval length, the coding coefficient, the first coding interval and the second coding interval to obtain a coded value; anda coding result is generated according to the coded value and then output. Accordingly, lossy compression of binary data can be well achieved, the compression capacity is high, and the compression effect is good.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data encoding method, device and storage medium. Background technique [0002] Data compression refers to a technical method to reduce the amount of data to reduce storage space and improve its transmission, storage and processing efficiency without losing information. [0003] Existing data compression techniques include lossy compression and lossless compression. For compressed data restoration, lossless compression refers to the use of compressed data for reconstruction (or restoration, decompression). The reconstructed data and The original data is exactly the same, while lossy compression refers to the use of compressed data for reconstruction. The reconstructed data is different from the original data, but it will not lead to misunderstanding of the information expressed by the original data. At present, there are many methods of data compression, and data with...
