Perceptual quality of color images of natural scenes transformed in CIELUV color space

Transformations of digitized color images in perceptually-uniform CIELUV color space and their perceptual relevance were investigated. Chroma veriation was chosen as the first step of a series of investigations into possible transformations (including lightness, hue-angle, chroma, ect.) To obtain the information about the perceptual consequences of the chosen transormations, perceptual image quality, naturalnessm and colorfoulness were measured by means of scaling. the results suggest that in general a more colorful image than the original one is preferred.
