HPRT-YOLO dataset Part2-train

HPRT-YOLO Dataset (A fused UAV maritime search-and-rescue object detection dataset)
This dataset is designed for small-object detection in UAV-based maritime search and rescue (SAR) and water-surface surveillance scenarios. It is formed by integrating two public datasets: SeaDronesSee and An Ensemble Deep Learning Method with Optimised Weights for Drone-Based Water Rescue and Surveillance.
• Source Dataset 1: SeaDronesSee
It contains 14,211 maritime UAV images with 6 original labels: ignored, swimmer, boat, jetski, life-saving appliance, buoy, and provides an official train/val/test split of 8,914/1,547/3,750. The data covers diverse coastal/offshore/harbor environments and includes challenges such as complex sea states, glare, and background clutter.
• Source Dataset 2: Drone-Based Water Rescue and Surveillance
It includes 3,613 images (train/val/test: 2,766/333/514) annotated with 6 classes: human, wind/sup-board, boat, kayak, buoy, sailboat.
To build HPRT-YOLO, we performed unified data cleaning, label alignment, and class remapping across the two sources, and obtained a fused dataset with 8 classes: ignored, human, boat, jetski, buoy, life-saving appliance, wind/sup-board, kayak.

To improve generalization under complex maritime conditions, we apply random cropping, scaling, flipping, rotation, and Mosaic augmentation during training; augmentation is disabled for validation and inference.

Because the dataset is relatively large, it is uploaded here in separate parts. The following is Part 2, which contains the train set.
