• 02:21, 10 December 2025 Annayu talk contribs created page Neural Network Implementation of S-CIELAB for Perceptual Color Metrics (Created page with "== Abstract == The Spatial CIELAB (S-CIELAB) metric is a widely used perceptual color-difference measure that incorporates both chromatic appearance and spatial properties of the human visual system. Despite its accuracy, S-CIELAB is computationally expensive due to its multi-stage processing pipeline, including opponent-color transformation, frequency-dependent spatial filtering, and nonlinear post-processing. Moreover, these filtering operations rely on fixed convoluti...")
