Claim 16:
17. A terminal, comprising:
at least one memory configured to store program instructions;
at least one processor configured to execute the program instructions which, when being executed by the at least one memory, cause the at least one processor to perform steps comprising:
receiving a first color image by an encoder, wherein the first color image comprises at least two portions of the first color image located at different locations of the first color image;
encoding whether a color consistency relationship between the at least two portions of the first color image exists into global information and local information; and
outputting, by the encoder, at least one feature map comprising the global information and the local information,
wherein:
the encoder comprises a plurality of first convolutional blocks, each of the first convolutional blocks comprises a corresponding first convolutional layer with a first receptive field, and a corresponding second convolutional layer with a second receptive field,
the first receptive field and the second receptive field of each second convolutional block of the first convolutional blocks are determined using at least one of the first receptive field and the second receptive field of a corresponding first convolutional block of the first convolutional blocks, and each second convolutional block of the first convolutional blocks is subsequent to the corresponding first convolutional block of the first convolutional blocks;
the first receptive field is wider than the second receptive field; and
the global information is obtained by the corresponding first convolutional layer of one of the first convolutional blocks, and the local information is obtained by the corresponding second convolutional layer of the one of the first convolutional blocks.
