Hands-On Image Processing and Computer Vision with Python - Second Edition
By :
In this chapter, we explored a wide range of image enhancement techniques, from point-wise intensity transformations (e.g., negative, power-law, contrast stretching) and histogram-based methods (e.g., equalization and matching) to noise reduction using linear (mean, Gaussian) and nonlinear filters (median, bilateral, non-local means). We also introduced fuzzy logic–based enhancement, wavelet-domain fusion, and deep learning–based methods for low-light correction, denoising, dehazing, and super-resolution. Readers should now be able to implement these techniques in Python, apply them to improve image quality, and interactively explore their effects using the Streamlit app. In the following chapter, we shall continue discussing more image enhancement techniques based on image derivatives and gradients.
