YOLO26手势识别项目实战2-石头剪刀布实时检测系统，其能识别检测出3种手势手语：names: ['Rock','Paper','Scissors']
具体图片见如下：
第一步：YOLO26介绍
YOLO26采用了端到端无NMS推理，直接生成预测结果，无需非极大值抑制（NMS）后处理。这种设计减少了延迟，简化了集成，并提高了部署效率。此外，YOLO26移除了分布焦点损失（DFL），从而增强了硬件兼容性，特别是在边缘设备上的表现。
模型还引入了ProgLoss和小目标感知标签分配（STAL），显著提升了小目标检测的精度。这对于物联网、机器人技术和航空影像等应用至关重要。同时，YOLO26采用了全新的MuSGD优化器，结合了SGD和Muon优化技术，提供更稳定的训练和更快的收敛速度。
