Claim 2:
3. The classifying method according to claim 2, wherein the performing a convolution operation on the imaging sequence corresponding to the 3D MRI image to obtain segment masks corresponding to each time of convolution operation comprises:
performing a first-layer convolution operation on the imaging sequence corresponding to the 3D MRI image to obtain a segment mask M1 corresponding to the first layer;
performing a second-layer convolution operation on the segment mask M1 to obtain a segment mask M2 corresponding to the second layer;
performing an m+1th-layer convolution operation on a segment mask M2 to obtain a segment mask M (m+1) corresponding to the m+1th layer, wherein m is a natural number greater than 2;
performing a nth-layer convolution operation on the segment mask M(m+1) to obtain a segment mask Mn corresponding to the nth layer;
wherein n is a natural number greater than m+1.
