IMSH
A module in CoReFuse-Med that performs intra-modality spatial harmonization using parameter-free 3×3×3 average pooling.
Timeline (last 90 days)
CoReFuse-Med splits fusion into two stages, keeping an overall three-stream, symmetric U-shaped segmentation network structure that contains three modules: LACE, IMSH and MBCF.
IMSH uses parameter-free 3×3×3 average pooling to decompose features into a structural base and a residual; the base uses competitive Softmax weights to select reliable anatomical structures, the residual is filtered of resampling artifacts by a shared Sigmoid gate, and finally lightweight DSConv3D integrates and writes back the result.
Ablation experiments show that on EPVS the Baseline achieves a DSC of 0.7146, and combining LACE+IMSH+MBCF reaches 0.7322.
