Claim 4:
5. The image processing method according to claim 4, wherein converting the input image or the feature map of the input image into a number F*F of the target input images or the target feature maps comprises:
performing down-sampling on the input image or the feature map of the input image by a step size N to obtain a number F*F of the target input images or the target feature maps, wherein the sampling formula is:

Oi,j(x,y)=I(xN+i,yN+j), wherein I and O represent the feature map of the input image or the input image and the target input image or the target feature map, respectively, and i and j are indexes established for the plurality of converted target input images or target feature maps, and i ∈[0,F), j ∈ [0,F), x and y are abscissa and ordinate of a pixel in a corresponding target input image or target feature map, respectively, and x∈[0,W′), y∈[0,H′), W′=L(W/N), H′=L(H/N), xN+i and yN+j are index values of a pixel in the input image or the feature map of the input image, U(·) represents a ceiling function, L(·) represents a floor function, and W and H represent the width and height of the feature map of the input image or the input image, respectively, W′ and H′ represent the width and height of the target input image or the target feature map, respectively.
