The YOLOv8 detection model is a powerful tool for various computer vision tasks including face, hand, and person detection. In this guide, we will explore how to utilize the YOLOv8 model alongside some datasets to boost your AI projects. Let’s embark on this exciting journey step-by-step!

Getting Started with Datasets

You will need to work with several datasets to effectively train and test your YOLOv8 model. Below is a list of datasets you can use:

• Face Datasets:
  • Anime Face CreateML
  • xml2txt
  • AN
  • Wider Face
• Hand Datasets:
  • AnHDet
  • Hand Detection
• Person Datasets:
  • COCO 2017 (only person)
  • AniSeg
  • SkyTNT Anime Segmentation
• Fashion Dataset:
  • DeepFashion2

Model Information

Here are some models you can use with their corresponding mean Average Precision (mAP) values:

Model                       Target                  mAP 50             mAP 50-95
face_yolov8n.pt            2D realistic face       0.660              0.366
face_yolov8s.pt            2D realistic face       0.713              0.404
hand_yolov8n.pt            2D realistic hand       0.767              0.505
person_yolov8n-seg.pt      2D realistic person     0.782 (bbox)

How to Set Up and Use the YOLOv8 Model

Let’s continue with the process of setting up and running the YOLOv8 model. Consider it like baking a cake: you need the right ingredients (model, data) and the right method (code) to get a delicious result!

• Step 1: Install Dependencies

  Ensure you have the required libraries installed. Use pip for installation:

  pip install ultralytics huggingface-hub opencv-python Pillow

• Step 2: Download the Model from Hugging Face

  Now, import the necessary libraries and download the YOLO model:

  from huggingface_hub import hf_hub_download
  from ultralytics import YOLO
  
  path = hf_hub_download('Bingsuadetailer', 'face_yolov8n.pt')
  model = YOLO(path)

• Step 3: Load an Image and Make Predictions

  Load an image and let the model predict:

  import cv2
  from PIL import Image
  
  img = 'https://farm5.staticflickr.com/41394887614566_6b57ec4422_z.jpg'
  output = model(img)
  pred = output[0].plot()
  
  pred = cv2.cvtColor(pred, cv2.COLOR_BGR2RGB)
  pred = Image.fromarray(pred)
  pred.show()

Troubleshooting Common Issues

While using the YOLOv8 detection model, you might run into some challenges. Here are a few common issues and how to resolve them:

• Model Download Error: If you encounter issues with model downloading, check your internet connection or re-validate the URLs provided.
• Image Not Showing: Ensure that the image path is correct and accessible. If you use a URL, make sure it’s valid.
• Unsafe Files Warning: If you receive warnings regarding unsafe files (particularly relating to `getattr`), ensure you only use files downloaded from trusted sources like the official Ultralytics repository or Hugging Face.
