Detailed structure of the Channel Enhancement Branch and the Position Enhancement Branch in the AKSA module. The Channel Enhancement Branch implements a Multi-scale Channel Attention (MCA) pathway that aggregates global channel context and applies multi-scale filters to reweight informative channels. The Position Enhancement Branch implements a Positional Attention (PA) pathway that produces a position-aware map to emphasize discriminative regions. The two branch outputs are then concatenated and fused by a lightweight gating unit to form the final enhanced feature.
