Modeling and evaluation of multimodal perceptual quality [PDF]

open access: yesIEEE Signal Processing Magazine, 1997
The increasing performance requirements of multimedia modalities, carrying speech, audio, video, image, and graphics emphasize the need for assessment methods of the total quality of a multimedia system and methods for simultaneous analysis of the system components. It is important to take into account still more perceptual characteristics of the human

Perceptual evaluation of color gamut mapping algorithms [PDF]

open access: yesColor Research & Application, 2008
AbstractThe recommendation of the CIE has been followed as closely as possible to evaluate the accuracy of five color gamut mapping algorithms (GMAs)—two nonspatial and three spatial algorithms—by psychophysical experiments with 20 test images, 20 observers, one test done on paper and a second one on display.

Visual Saliency Prediction and Evaluation across Different Perceptual Tasks. [PDF]

open access: yesPLoS ONE, 2015
Saliency maps produced by different algorithms are often evaluated by comparing output to fixated image locations appearing in human eye tracking data. There are challenges in evaluation based on fixation data due to bias in the data.
