DRAgent: Discriminative Reasoning Agent for Referring Expression Segmentation

DRAgent introduces a discriminative reasoning framework for Referring Expression Segmentation that replaces direct coordinate prediction with a two‑stage selection process. First, a detector generates candidate boxes; then a multimodal large language model (MLLM) discriminates the correct target through high‑recall screening and instance‑wise verification. The chosen box serves as a spatial prompt for a foundation segmentation model, and a self‑consistency‑filtered data pipeline is used for LoRA‑based fine‑tuning, yielding competitive results on RefCOCO, RefCOCO+, and RefCOCOg.

FlashReg: GPU-Accelerated 3-Clique Point Cloud Registration for Real-Time Correspondence-to-Pose Estimation

FlashReg is a GPU‑accelerated method for point cloud registration that bypasses the construction of dense second‑order compatibility graphs. It builds a sparse second‑order graph directly from a binary first‑order graph using Fast First‑ and Second‑Order Graph (FFSOG) construction, then performs a dataflow‑optimized 3‑clique search to select correspondence pivots and enumerate triples. On indoor and outdoor benchmarks, FlashReg achieves 2–3× lower correspondence‑to‑pose latency than TurboReg while using roughly half the peak tensor memory on an embedded GPU, making it suitable for high‑throughput onboard perception pipelines.

Localization-Infused Vision-Language Semantic Fusion for Text-Guided Medical Image Segmentation

The paper introduces LoG, a localization‑infused vision‑language fusion framework for text‑guided medical image segmentation. LoG jointly performs multi‑scale target localization to explicitly capture target‑oriented semantics and employs three levels of localization‑infused fusion—feature, attention, and loss—to integrate spatial information into segmentation. Experiments on three benchmark datasets across three imaging modalities show that LoG consistently outperforms state‑of‑the‑art methods.
