Hands-On Image Processing and Computer Vision with Python - Second Edition
By :
This chapter covered derivative-based image enhancement, including classical methods like unsharp masking and entropy-based contrast enhancement, gradient- and Laplacian-based edge detectors (Sobel, Prewitt, Roberts, Canny, LoG/DoG), multiscale techniques with Gaussian and Laplacian pyramids, and advanced approaches such as ridge/structured edge detection, guided filtering, anisotropic diffusion, and deep learning–based detectors (HED, PiDiNet).
Python implementations using scikit-image, OpenCV, and scipy illustrated practical applications, while an interactive Gradio app demonstrated Canny edge detection, enabling readers to experiment with thresholds and visualize results. Readers should now be able to implement derivative-based enhancements, detect edges with various filters, perform multiscale analysis, and explore both classical and deep learning–based edge detection in Python.
In the next chapter, we shall discuss image restoration techniques.
