Image processing techniques
Filter, threshold and detect edges.
📖 Key ideas
- Blurring (Gaussian) reduces noise.
- Thresholding turns images into black and white.
- Edge detection: Canny finds outlines.
- Morphology (erode, dilate) cleans shapes.
- Contours find object boundaries.
💡 Real-life example: Image processing is cleaning a dusty window so the view (objects) becomes clear.
