**Summary** 1. SegVG replaces traditional bounding boxes with pixel-level precision, greatly improving AI’s object localization. 2. The framework utilizes a multi-task encoder-decoder to separately handle bounding box regression and segmentation. 3. A triplet alignment module ensures AI aligns its queries, text, and visual data smoothly. 4. SegVG has outperformed existing algorithms on multiple datasets. 5. The framework is open-source, promoting broad collaboration and development in AI vision.
