Meta:SAM 3 目标物体精准检测、分割与跟踪大模型

from 每日AI · host 每日新闻

SAM 3 是由 Meta 公司开发的全新通用分割模型,旨在通过文本短语或图像示例实现对目标物体的精准检测、分割与跟踪。该模型引入了“可提示概念分割”(PCS)任务,使其不仅能识别单个物体,还能捕捉图像或视频中符合某一概念的所有实例。为了支撑这一技术,研究团队构建了一个包含 400万个唯一概念标签 的大规模高质量数据集,并开发了结合人工与人工智能的高效数据引擎。SAM 3 采用解耦的检测器与跟踪器架构,配合创新的“存在头”设计,显著提升了在开放词汇环境下的识别准确度。此外,该系统支持交互式微调,用户可以通过增加正负示例点来修正分割结果,使其在性能上超越了前代版本。这一成果通过开源模型代码、基准测试集及在线演示,为多模态视觉人工智能领域提供了强大的基础工具。
