Supported Models

We support the following YOLOv8 models:

• yolov8l: YOLOv8-Large
• yolov8n: YOLOv8-Nano
• yolov8l-face: YOLOv8-Large trained on the WIDER FACE dataset
• yolov8n-face: YOLOv8-Nano trained on the WIDER FACE dataset
• yolov8l-world: YOLOv8-Large used for open-vocabulary object detection (specify any object you want to detect)
• yolov8s-world: YOLOv8-Small used for open-vocabulary object detection (specify any object you want to detect)

Output Format

The model returns a dictionary with the following structure:

{
  "boxes": [
    {
      "x1": 281.36834716796875,
      "y1": 114.6531982421875,
      "x2": 937.3942260742188,
      "y2": 712.1339111328125,
      "width": 656.02587890625,
      "height": 597.480712890625,
      "confidence": 0.9540532827377319,
      "class_number": 0,
      "class_name": "person"
    },
    {
      "x1": 932.1299438476562,
      "y1": 610.4577026367188,
      "x2": 1279.69775390625,
      "y2": 711.7876586914062,
      "width": 347.56781005859375,
      "height": 101.3299560546875,
      "confidence": 0.6923111081123352,
      "class_number": 56,
      "class_name": "chair"
    }
  ],
  "frame_number": 0
}

Each box in the "boxes" array represents a detected object. The fields "x1", "y1", "x2", "y2" represent the coordinates of the top left and bottom right corners of the bounding box respectively. The "width" and "height" fields represent the width and height of the bounding box. The "confidence" field represents the confidence score of the detection. The "class_number" and "class_name" fields represent the class of the detected object.

Classes

If you are using the yolov8l-world or yolov8s-world models, you can specify any object you want to detect using the classes parameter.

Otherwise, there are 80 classes to choose from for detections. These are the possible detection classes:
