Claim 5:
6. The method according to claim 5, wherein calculating the difference between the generated-character feature map of the target feature layer and the sample character feature map of the target feature layer comprises:
calculating an absolute value of a difference value between a pixel value of a pixel at each position in the generated-character feature map and a pixel value of a pixel at a corresponding position in the sample character feature map to obtain a difference between the pixel at each position in the generated-character feature map and the pixel at the corresponding position in the sample character feature map; and
determining a pixel difference between the generated-character feature map and the sample character feature map according to differences between pixels at a plurality of positions in the generated-character feature map and pixels at corresponding positions in the sample character feature map.
