"Witryna18 lut 2024 · In order to present a physically significant model, Retinex's theory [ 13] assumes that the image is decomposed into two parts, illumination and reflectance. The early methods such as single-scale retinex [ 25 ], multiscale retinex (MSR) [ 26] aimed to improve reflectance, which treats the reflectance component as the final output. " - Import retinex
