Abstract:
A method for producing a numerical representation of user perceived overall image quality of a digital test image, comprising:(a) creating a digital reference image series of a reference scene, each digital reference image differing from each other digital reference image in at least one perceptual attribute, wherein each digital reference image has a corresponding numerical representation of overall image quality; (b) iteratively displaying to a user one of the digital reference images and comparing the displayed digital reference image with the digital test image, the user indicating perceived overall image quality between the displayed digital reference image and the digital test image, the next displayed digital reference image being selected based on the user indication of perceived overall image quality; (c) inferring the numerical representation of the digital test image from the iteratively displaying and comparing; and (d) recording the inferred numerical representation corresponding to the digital test image.
