Abstract: An information processing method is disclosed. The method includes: obtaining initial feature information of to-be-queried information; performing feature processing on the initial feature information of the to-be-queried information, to obtain target feature information of the to-be-queried information, where the feature processing includes at least feature dimension processing used to process a data dimension of the initial feature information of the to-be-queried information to be a preset dimension; performing a first retrieval operation on m pieces of candidate information based on the target feature information of the to-be-queried information, to obtain a first retrieval result; and performing a second retrieval operation on the first retrieval result based on the initial feature information of the to-be-queried information, to obtain result information corresponding to the to-be-queried information. The method can quickly and efficiently implement information retrieval.

Abstract: A two-dimensional code generation method is disclosed, including: obtaining M colors and a characteristic value of each color in a target color path; determining a target mapping relationship based on a magnitude relationship between characteristic values of the M colors in the target color path; obtaining a target link, and generating a bitstream corresponding to the target link; and determining a color corresponding to each piece of element information in the bitstream, and generating a target two-dimensional code based on the color corresponding to each piece of element information in the bitstream. According to the two-dimensional code generation method, a code scanning side can restore, based on a magnitude relationship between characteristic values of colors of elements in the scanned two-dimensional code, a correspondence that is between colors and element information and that is used for generating the two-dimensional code, to accurately identify content in the two-dimensional code.
