A Windows and Linux GUI application for drawing bounding boxes around objects in images to create labeled training data for YOLO v2/v3 object detection models. It also extracts frames from video files and generates the config files needed to train custom Darknet/YOLO detectors.

Use cases

• label bounding boxes on images for yolo training
• create training data for custom object detection model
• extract frames from video for image labeling
• annotate images for darknet yolo v3
• generate obj.names and train.txt files for yolo training

When to choose

• you are training YOLO v2/v3 (Darknet) models on custom objects and need labeled images
• you want a lightweight desktop annotation tool that outputs YOLO-format labels directly
• you need to extract frames from video files and label them in one workflow

When to avoid

• you need annotations for other model formats like Pascal VOC or COCO
• you want a modern, actively maintained annotation tool with web collaboration
• you are training YOLOv4/v5 or newer models with different tooling ecosystems
