DH-V2: Geometry-Based Sampler Achieves 1,433x Compression for Edge Perception
Researchers present Double-Helix Vision (DH-V2), a geometry-based visual sampler that compresses 2D images into compact 1D signals using golden-ratio-inspired spiral trajectories. At 4K resolution, it achieves a 1,433x compression ratio while running in 0.52ms on CPU-only hardware, and includes a JSON-serializable Robotics API for bandwidth-constrained perception.
New Sub-Semantic Image Segmentation Method DETECTURE Introduced by Researchers, Outperforms Baselines
Researchers propose a new category of image segmentation called sub-semantic, which uses language to partition images into stable appearance patterns rather than whole objects. They introduce DETECTURE, a method that couples a vision-language model with SAM 3 to overcome three failure modes, and create a new dataset called TextureADE derived from ADE20K. DETECTURE achieves the strongest performance on several datasets compared to baselines.
