Contrast Enhancement Based on Layered Difference Representation of 2D Histograms (2013, background): “Naik and Murthy [13] generalized HE to enhance the contrast of color images and developed an algorithm to avoid the gamut problem during the enhancement.”
Underwater Image Enhancement via Medium Transmission-Guided Multi-Color Space Embedding (2021, methodology): “Inspired by the traditional enhancement algorithms that operate in various color spaces [23], [43], we extract features in three color spaces (RGB, HSV, and Lab) where the same image has different visual representations in various color systems as shown in Fig.”
