The data to be translated: SAGA is a cutting-edge technology jointly developed by Shanghai Jiao Tong University and Huawei, achieving efficient segmentation in 3D scenes with millisecond-level performance. By integrating 2D segmentation and 3D Gaussian techniques, it overcomes the challenges of previous methods and supports multi-granularity segmentation. The paper has been published on arXiv, demonstrating exceptional performance in benchmark tests, especially achieving nearly 1000 times acceleration in 3D segmentation speed.
