Claim 18:
19. The system of claim 18,
wherein a low-frequency split spectral sub-tensor of the plurality of spectral sub-tensors corresponds to the at least one low frequency band, a high-frequency split spectral sub-tensor of split spectral sub-tensors corresponds to the at least one high-frequency band;
wherein performing the inverse transform of the plurality of the split spectral sub-tensors from the frequency domain to the spatial domain includes generating a low-detail spatial sub-tensor from the low-frequency split spectral sub-tensor of the plurality of spectral sub-tensors, and generating a high-detail spatial sub-tensor from the high-frequency split spectral sub-tensor of the plurality of spectral sub-tensors;
wherein the set of instructions includes instructions, which, when executed by the one or more processors, cause merging the low-detail spatial sub-tensor with a tensor of a smaller dimension layer of a decoder, and merging the high-detail spatial sub-tensor with a tensor of a greater dimension layer of the decoder, the decoder generating the output image data.
