ORSIFlow: Saliency-Guided Rectified Flow for Optical Remote Sensing Salient Object Detection

ORSIFlow is a saliency‑guided rectified flow framework for optical remote sensing salient object detection that reframes the task as deterministic latent flow generation. It uses a frozen variational autoencoder to produce saliency masks in a compact latent space, allowing efficient inference with few steps. The method incorporates a Salient Feature Discriminator for global semantic discrimination and a Salient Feature Calibrator for precise boundary refinement, achieving state‑of‑the‑art performance on multiple public benchmarks.
