HCTNet: a hierarchical hybrid convolution-transformer network with bidirectional cross-attention fusion for brain tumor MRI classification

HCTNet is proposed, a four-stage hierarchical hybrid network in which a convolutional Local Feature Extractor runs in parallel with a transformer-based Global Feature Extractor, which outperforms additive and concatenation fusion and exposes complementary region-level and pixel-level evidence concentrated within the br...
