YOLOv8 hand pose estimation uses pose/keypoint detection to locate hands and predict landmark positions representing the wrist, fingers, and individual finger joints. YOLOv8 supports pose training and inference, so it can be fine-tuned on a hand-keypoint dataset for applications such as gesture recognition, sign-language systems, human-computer interaction, robotics, and AR/VR. A common hand landmark structure […]

The YOLOv8 Pose dataset format extends the standard YOLO object detection format by adding keypoint coordinates to each labeled object. Every training image has a corresponding text label file containing the class ID, normalized bounding box coordinates, and the defined keypoints. Depending on the dataset configuration, each keypoint can contain either x, y coordinates or

The YOLOv8 COCO class list contains 80 object categories that pretrained YOLOv8 detection models can recognize. These classes come from the COCO dataset and include common objects such as people, cars, animals, furniture, food items, sports equipment, and household objects. Each class has a unique ID from 0 to 79, which YOLOv8 uses internally during

Training YOLOv8 Pose on a custom dataset allows you to detect objects and predict specific keypoints that describe their pose or structure. Instead of being limited to the standard human body keypoints used by pretrained pose models, you can define your own classes, keypoint locations, and skeleton structure for applications such as animal pose estimation,

YOLOv8 release notes and updates document the changes made to the Ultralytics package that supports YOLOv8 and other Ultralytics YOLO models. Since YOLOv8 was introduced on January 10, 2023, the surrounding Ultralytics software has received frequent updates covering training, prediction, export, deployment, bug fixes, compatibility, and performance. YOLOv8 remains supported inside the modern Ultralytics framework

The YOLOv8 CSPDarknet backbone is responsible for extracting meaningful visual features from input images before those features are passed to the neck and detection head. Its design builds on CSP-style feature extraction principles while using C2f modules to improve gradient flow, feature reuse, and computational efficiency. This backbone helps YOLOv8 identify useful patterns at different

Exporting YOLOv8 to ONNX format allows a trained Ultralytics model to run outside the normal PyTorch environment. ONNX, or Open Neural Network Exchange, provides a standardized model representation supported by runtimes and deployment tools such as ONNX Runtime, OpenCV DNN, TensorRT conversion pipelines, and other inference systems. Ultralytics provides built-in ONNX export through both the

YOLOv8 Non-Maximum Suppression, or NMS, is a post-processing step used to remove redundant overlapping bounding boxes from object detection predictions. A detector may initially produce several boxes around the same object. NMS compares their confidence scores and overlap, keeps the strongest detection, and suppresses weaker overlapping boxes. Current Ultralytics prediction settings expose parameters such as

The YOLOv8 IoU threshold controls how strongly overlapping bounding boxes are treated during prediction post-processing and validation. IoU, or Intersection over Union, measures the amount of overlap between two bounding boxes. In Ultralytics prediction mode, the iou argument is primarily used as the IoU threshold for Non-Maximum Suppression, where overlapping predictions are filtered to reduce

The YOLOv8 Task Aligned Assigner is a training component used to match model predictions with ground-truth objects. It helps determine which prediction points should be treated as positive samples during training by considering both classification confidence and localization quality. This improves the alignment between object classification and bounding box prediction, allowing YOLOv8 to learn more
