Claim 13:
14. The computer-implemented method of claim 10, further comprising:
receiving the first color image by an encoder,
processing, by the encoder, the received first color image in such a manner that whether the color consistency relationship between the first portion of the first color image and the second portion of the first color image exists is encoded into the global information and the local information, to obtain the at least one feature map, and
outputting, by the encoder, the at least one feature map,
wherein:
the encoder comprises a plurality of second convolutional blocks, and each of the second convolutional blocks comprises a corresponding third convolutional layer with a third receptive field, and a corresponding fourth convolutional layer with a fourth receptive field,
the third receptive field and the fourth receptive field of each fourth convolutional block of the second convolutional blocks are determined using at least one of the third receptive field and the fourth receptive field of a corresponding third convolutional block of the second convolutional blocks, and each fourth convolutional block of the second convolutional blocks is subsequent to the corresponding third convolutional block of the second convolutional blocks;
the third receptive field is wider than the fourth receptive field; and
the global information is obtained by the corresponding third convolutional layer of one of the second convolutional blocks, and the local information is obtained by the corresponding fourth convolutional layer of the one of the second convolutional blocks.
