What is YOLO?
YOLO stands for You Only Look Once. It’s a computer program that helps identify objects in images or videos. For this project, YOLO is trained to detect people in a video.
Imagine YOLO as a fast scanner that looks at the entire image in one go. It draws boxes around objects it identifies, like people, and gives each object an ID.
This makes YOLO a great choice for real-time applications like this project, where it tracks people as they move.
How Does It Predict Age and Gender?
After YOLO detects a person, the system looks at their face to predict their age and gender.
- Age Prediction: The system guesses the person’s age by analyzing patterns like wrinkles or smoothness in their face.
- Gender Prediction: The system predicts whether the person is male or female by looking at features like jaw shape or facial structure.
These predictions are made using models trained on lots of images of people of different ages and genders.
How Does It Describe a Person?
The system also provides a brief description of the person using a special program called BLIP. This program analyzes the person’s appearance and creates a sentence like, “A man wearing glasses” or “A woman with a red shirt.”
This description adds an extra layer of detail and makes the system more interactive.
How Does It All Work Together?
Here’s what happens step by step:
- The camera captures a live video feed.
- YOLO detects people in the video and tracks them as they move.
- The system predicts the age and gender of each detected person.
- It also generates a short description of the person.
- All this information is displayed on the video feed in real-time!
