Abstract
We evaluated bidirectional feature fusion for hyperspectral classification under 15% band corruption. A deterministic paired simulation generated 72 cases and preserved a boundary-condition stratum. Mean spectral-spatial accuracy changed from 0.580 to 0.627; the paired difference was +0.046 (95% interval +0.044 to +0.049). The result is limited to the stated simulation and is reported with a reproducible result artifact.
