A comprehensive presentation guide for Digital Image Processing S. Jayaraman, S. Esakkirajan, and T. Veerakumar
Fields of digital image processing slides | PPT - Slideshare digital image processing jayaraman ppt
✅ 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.
