Effectiveness of 2 3 montage augmentation. Effectiveness comparison of YOLOv7 before and after montage augmentation across the ID validation and test sets, and an OOD test set, with a focus on the OOD scenario that involves a change in devices.

Effectiveness of 2 3 montage augmentation. Effectiveness comparison of YOLOv7 before and after montage augmentation across the ID validation and test sets, and an OOD test set, with a focus on the OOD scenario that involves a change in devices.2至3帧拼接数据增强的有效性。针对YOLOv7在拼接数据增强前后的效果进行对比分析，覆盖分布内（ID，In-Distribution）验证集、测试集以及分布外（OOD，Out-of-Distribution）测试集，重点聚焦于涉及设备变更的分布外场景。
