Abstract
Although dual-stream architectures have achieved remarkable success in single
image reflection removal, they fail to fully exploit inter-layer
complementarity in their physical modeling and network design, which limits the
quality of image separation. To address this fundamental limitation, we propose
two targeted improvements to enhance dual-stream architectures: First, we
introduce a novel inter-layer complementarity model where low-frequency
components extracted from the residual layer interact with the transmission
layer through dual-stream architecture to enhance inter-layer complementarity.
Meanwhile, high-frequency components from the residual layer provide inverse
modulation to both streams, improving the detail quality of the transmission
layer. Second, we propose an efficient inter-layer complementarity attention
mechanism which first cross-reorganizes dual streams at the channel level to
obtain reorganized streams with inter-layer complementary structures, then
performs attention computation on the reorganized streams to achieve better
inter-layer separation, and finally restores the original stream structure for
output. Experimental results demonstrate that our method achieves
state-of-the-art separation quality on multiple public datasets while
significantly reducing both computational cost and model complexity.
