1. A method, applied to a decoding device, for decoding data for picture or video processing from a bitstream, the method comprising:
obtaining, from the bitstream, segmentation information relating two or more feature map processing layers of a plurality of cascaded layers and a part of a feature map processed by the two or more feature map processing layers;
obtaining, from the bitstream, two or more sets of feature map elements,
wherein the two or more sets of feature map elements relate to two or more feature maps, respectively, such that each set of feature map elements relates to one of the two or more feature maps, and
wherein obtaining the feature map elements from the bitstream is based on the segmentation information:
simultaneously inputting, based on the segmentation information, each of the two or more sets of feature map elements into a different one of two or more feature map processing layers out of the plurality of cascaded layers; and
obtaining decoded data for picture or video processing as a result of processing each of the feature maps in two or more feature map processing layers of the plurality of cascaded layers,
wherein each of the feature maps processed in two or more feature map processing layers of the plurality of cascaded layers has a resolution different from each of the other two or more feature maps processed in two or more feature map processing layers of the plurality of cascaded layers, and
wherein the processing of each of the feature maps in two or more feature map processing layers of the plurality of cascaded layers includes upsampling.
