An integer coding method, device and storage medium

Abstract

The embodiment of the invention discloses a method, a device and a storage medium for the integer coding. The embodiment of the invention comprises the following steps: obtaining multiple target sample integers; obtaining the probability that each target sample integer appears in a sample integer set to obtain the occurrence probability corresponding to each target sample integer; constructing aninteger sequence according to each target sample integer and occurrence probability corresponding to the target sample integer; dividing the integer sequence according to the occurrence probability corresponding to the target sample integer, and constructing an integer code book based on the division result; coding the corresponding integer based on the integer code book; the sequence elements ofthe integer sequence comprise the target sample integer and occurrence probability corresponding to the target sample integer. The scheme can construct the integer code book according to the sample integer and occurrence probability corresponding to the sample integer. The integer code book constructed by this scheme is moderately sized. The difficulty of coding compression can be reduced and thecoding compression efficiency of integers can be improved by coding the integer using the integer code book.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an integer encoding method, device and storage medium. Background technique [0002] Currently, in order to reduce the amount of data, the data may be compressed and encoded. For example, image data can be correspondingly encoded to reduce the amount of data required to represent a digital image, so as to facilitate image storage and transmission. [0003] Integer compression is a very important topic at present. The so-called integer compression is to encode the corresponding integers such as decimal integers to achieve the effect of compressing data. At present, Huffman (Huffman) coding is generally used for integer compression. However, when using Huffman (Huffman) coding to encode integers, if the range of integers is too large (such as the maximum value of the range is 2 to the power of 32 or even 2 to 64 power), the required code table will be very large and the...

At present, Huffman (Huffman) coding is generally used for integer compression. However, when using Huffman (Huffman) coding to encode integers, if the range of integers is too large (such as the maximum value of the range is 2 to the power of 32 or even 2 to 64 power), the required code table will be large and difficult to encode, resulting in relatively low encoding and compression efficiency for integers
