🧙‍♂️ Harry Potter Invisibility Cloak

This mini-project recreates the Harry Potter–style Invisible Cloak effect using OpenCV and NumPy in Python.
By detecting a specific color (blue here) from the webcam and replacing that color with the background, it creates an illusion of invisibility in real time.

🧠 How It Works

1. The camera first captures the background (without the person).
2. When the person enters the frame wearing a specific color cloak (default: blue), the program detects that color using the HSV color space.
3. That colored region is replaced with the previously captured background, making the cloak area appear invisible.
4. The result is shown live using OpenCV’s video window.
