✅ Chapter 3 – Spatial Domain Enhancement (25–30 slides)

• Gray level transformations (contrast stretching, thresholding)
• Histogram processing (equalization, matching)
• Smoothing filters (average, median)
• Sharpening filters (Laplacian, Sobel, Prewitt)
• Key difference: Jayaraman uses MATLAB-style examples heavily.

• First-order derivative operators: Sobel, Prewitt, and Roberts operators.
• Second-order derivative operators: The Laplacian operator and the Laplacian of Gaussian (LoG).
• Canny Edge Detector: Discussed as an optimal edge detector, utilizing smoothing, gradient calculation, non-maximum suppression, and hysteresis thresholding.

• Structuring elements, erosion, dilation, opening, and closing.
• Applications: removing small objects, filling holes, extracting boundaries. Mira used morphological closing to connect broken strokes in a scanned handwritten document.
