Abstract: Methods and apparatuses for recognizing a two-dimensional code are disclosed. In an implementation, a method comprises: identifying, by an electronic device, a two-dimensional code, wherein the two-dimensional code comprises an image region in the center and a ring region surrounding the image region, wherein the ring region comprises a code region including a first code region and a second code region, a first spacing region, and a second spacing region, wherein the first spacing region and the second spacing region are arranged between the first code region and the second code region, determining values corresponding to a plurality of code elements in the code region, and recognizing, by the electronic device based on the values, first information corresponding to the two-dimensional code.

Abstract: When probability estimation is performed in encoding and decoding processes, probability distribution of an unquantized image feature is estimated based on a hyperprior feature of the unquantized image feature via a first probability distribution estimation network, and then probability distribution of a quantized image feature is obtained through quantization. Alternatively, probability distribution of a quantized image feature is directly estimated based on a hyperprior feature of an unquantized image feature via a second probability distribution estimation network.

Abstract: In a method, an electronic device obtains to-be-encoded text, where the to-be-encoded text includes N characters; the electronic device determines a target coding mode for each of the N characters from X optional coding modes; the electronic device groups the N characters into M character fields based on the target coding mode for each character, and determines a target coding mode for each of the M character fields, where M is less than or equal to N; the electronic device encodes the M character fields based on the target coding mode for each character field to obtain a first binary character string; and the electronic device generates, based on the first binary character string, a two-dimensional code of a version corresponding to a length of the first binary character string.
