A real-time computer vision application that creates the illusion of invisibility using a solid blue-colored cloak and background subtraction techniques. Built with OpenCV and PyQt5 for an interactive GUI.
📷 Live Webcam Feed
→ Real-time video stream using OpenCV embedded in PyQt5.
🧥 Invisible Cloak Effect
→ Hides cloak based on blue color detection.
🧼 Noise Reduction
→ Smoothens mask with morphological operations (open → dilate → erode).
🖼️ Background Capture
→ Captures a clean, averaged background over 60 frames.
🔁 Mirror View
→ Flips video horizontally for natural webcam behavior.
💬 Voice Feedback
→ Text-to-speech guides user during background capture.
🌗 Lighting Detection
→ Skips background capture if lighting is too low.
🎨 Dark Mode GUI
→ Modern interface with a dark theme and live video preview.

cd opencv-invisibility-cloak pip install -r requirements.txt python main.py- Use a solid blue-colored cloak.
- Ensure even lighting — avoid shadows or reflections.
- Capture the background without the person.
