Claim 4:
5. The method according to claim 1, wherein the respectively performing the hierarchically dilated convolutions operation on the M enhanced feature maps of the slice by the deep neural network, to generate the superposed feature map of each enhanced feature map comprises:
for each enhanced feature map in the M enhanced feature maps:
respectively processing, by the device, the enhanced feature map by using K dilated convolution layers, to obtain K dilated feature maps of the enhanced feature map, K being an integer greater than 1;
processing, by the device, the enhanced feature map by a common convolution layer, to obtain convolution feature maps of the enhanced feature map; and
obtaining, by the device, the superposed feature map of the enhanced feature map based on the K dilated feature maps and the convolution feature maps of the enhanced feature map.
