10.48550/arXiv.2603.28584A saliency-guided rectified flow framework for efficient and state-of-the-art optical remote sensing salient object detection.
Abstract
Optical Remote Sensing Image Salient Object Detection (ORSI-SOD) remains challenging due to complex backgrounds, low contrast, irregular object shapes, and large variations in object scale. Existing discriminative methods directly regress saliency maps, while recent diffusion-based generative approaches suffer from stochastic sampling and high computational cost. In this paper, we propose ORSIFlow, a saliency-guided rectified flow framework that reformulates ORSI-SOD as a deterministic latent flow generation problem. ORSIFlow performs saliency mask generation in a compact latent space constructed by a frozen variational autoencoder, enabling efficient inference with only a few steps. To enhance saliency awareness, we design a Salient Feature Discriminator for global semantic discrimination and a Salient Feature Calibrator for precise boundary refinement. Extensive experiments on multiple public benchmarks show that ORSIFlow achieves state-of-the-art performance with significantly improved efficiency. Codes are available at: https://github.com/Ch3nSir/ORSIFlow.

WHY NOW
Computer Vision moved forward this cycle; last verified April 2026. Public score 7.0/10. Implementation evidence is present through a linked repository.
We propose ORSIFlow, a saliency-guided rectified flow framework, which performs saliency mask generation instead of direct discriminative prediction.
Explicitly stated in both the abstract and the contributions section as a core methodological contribution.
partial
We generate saliency masks in a compact latent space built by a frozen variational autoencoder... significantly reducing computational complexity.
Directly stated in the abstract and contributions, with the term 'significantly reducing computational complexity' used in the architecture description.
partial
enabling stable training and efficient inference with few steps.
Strongly implied by the critique of diffusion models requiring many steps and the claim of 'efficient inference with few steps' in the contributions.
partial
diffusion models typically rely on stochastic and curved denoising trajectories... requiring a large number of sampling steps... such stochastic generation may still struggle to preserve fine-grained structures and small salient objects.
Directly stated as a limitation of prior work in the analysis, though the evidence quote is from the critique section.
partial
the Salient Feature Discriminator performs relational modeling of global semantics
Explicitly stated in the methodology section describing the module's purpose.
partial
a Salient Feature Calibrator for precise boundary refinement.
Explicitly stated in the abstract and methodology as the module's purpose.
partial
Extensive experiments on multiple public benchmarks show that ORSIFlow achieves state-of-the-art performance
Directly stated in the abstract, though specific benchmark names and metrics are not provided in the given excerpts.
partial
ORSIFlow achieves superior performance while substantially reducing computational cost
Strongly supported by the abstract's claim of 'significantly improved efficiency' and the final summary statement.
