ABSTRACT This study investigates the fidelity of high‐resolution, colorimetrically reproduced digital images in rendering the perceived gloss of real‐world objects. The methodology employed two psychophysical experiments using 24 stimuli consisting of glass, metal, and stone. The first was a direct comparison of the perceived gloss between the real objects and their initial colorimetrically reproduced images. The second was a selection task where participants matched the gloss of the real objects to a set of algorithmically processed images. The findings reveal two key results: (1) The direct comparison demonstrated that digital colorimetric reproduction significantly reduced the perceived gloss compared to the real objects. (2) The subsequent image selection experiment indicated that the contrast component of gray level co‐occurrence matrix (GLCM) features is a significant predictor of the accuracy in reproducing the real objects' gloss. These results suggest that accurate gloss reproduction in digital displays is not solely dependent on colorimetric fidelity, but can be effectively achieved through the modulation of image contrast.
