SPEANet is a parameter‑efficient backbone for remote sensing object detection that incorporates fixed structural operators to enhance contour and frequency responses. It uses stage‑specific prior extraction and context‑conditioned response modulation, assigning smoothed contour and directional modeling to shallow features and a compact approximation‑detail interaction to deeper stages. Experiments on five benchmarks, including DOTA‑v1.0, DOTA‑v1.5, and DIOR‑R, show that SPEANet achieves high mAP scores (up to 78.55%) with only 23.0 M total parameters, of which the backbone accounts for 5.97 M.

The paper introduces SASC-USOD, a framework for underwater salient object detection that learns spatially adaptive coordination between two structural representations: a boundary-sensitive representation using Laplacian filtering and a region-coherent representation via dual-range anisotropic large-kernel aggregation. A spatial coordination module estimates the relative reliability of these representations and adaptively blends them based on image content. Experiments on USOD10K and USOD benchmarks show that SASC-USOD outperforms existing methods, reducing MAE by 4.07% and 23.53% respectively, and its lightweight variant achieves 21 FPS on an NVIDIA Jetson TX2 NX.

The paper introduces Feature Interaction Network (FINE), a lightweight semantic alignment module for feature fusion networks in object detectors. FINE refines low‑level features using high‑level contextual guidance through cross‑level attention, and employs Alignment‑Aware Token Sampling to reduce attention complexity. The resulting spatial‑channel modulation map selectively enhances semantically relevant pixels while preserving sub‑pixel localization, leading to improved detection accuracy with minimal computational overhead.
Infrared-visible image fusion (IVIF) is pivotal for multimodal perception, yet reconciling the inherent information disparity between thermal and textural features remains a fundamental challenge. Existing prior-guided methods often rely on static constraints that induce optimization conflicts or utilize extrinsic semantic priors from large-scale foundation models (e.
