    "abstract": "This paper addresses the question of whether subjects are able to assess the perceived time-varying quality of video sequences continuously. To this end, a method is used in which subjects continuously indicate the perceived image quality by moving a slider along a graphical scale. The slider's position on this scale is sampled at a constant rate of typically 1/sec. The temporal variations of the assessed quality of one particular sequence are compared with the results of another experiment in which the image quality of very short palindromically presented fragments of the video sequence was rated separately on a graphical scale. The results show that subjects can monitor image-quality variations almost instantaneously.",

He has been affiliated with the Vision Group of the Institute for Perception Research (IPO) since 1982, where his research focuses on both fundamental and applied psychophysics and psycho-metrics. From 1987 to 1992 his research on the fundamentals of perceptual image quality metrics was supported by a personal fellowship from the Royal Netherlands Academy of Arts and Sciences. Dr. de Ridder's current research interests include the development of new techniques for evaluating static and dynamic images, the multidimensional analysis of image quality, the optimization of color reproduction, and the subjective evaluation of stereoscopic displays.",

In 1992 he joined IPO, where he worked on perceptually relevant, quantitative modeling of certain artifacts in display systems, such as local and global color uniformity, moiré, loss of contrast through internal and external scattering, and geometry deformations. Recently he has become involved in the development of new evaluation techniques, in which display systems can be evaluated both swiftly and reliably.",
