YOLO v3 format of traffic signs dataset to train and test detector

🔄 Converts horizontal bounding boxes into oriented (rotated) boxes by prompting SAM-family models with your existing HBB annotations, no re-labeling. Includes model ensembling, confidence scoring, evaluation, format conversion, and hyperparameter tuning.

My own version to annotate dataset for YOLO format (Including multi-class labeling on the same image)

This developed algorithm transforms mask labels used in previous segmentation tasks into a format compatible with YOLO's label requirements. As a result, pre-prepared datasets can be used with YOLO-like detection-focused architectures.
