Figure 3. Main functional components of STFF, including channel attention, feature-derived coarse spatial modulation, and multi-receptive-field spatial attention. STFF: Scale-tuned feature fusion; GAP: global average pooling; GMP: global maximum pooling; MLP: multilayer perceptron; CA: channel attention; CPM: coarse spatial modulation; MSA: multi-receptive-field spatial attention; Conv: convolution.
