Visual evaluation of images
by Iris Sprow
Dear all,
Those who are working with images, are familiar with the difficulty of color representation in computer systems: one captures an image, scans it, or already has the file on his computer, works with it, saves it, puts it up on the Internet-and suddenly colors look differently than intended. When looking at the Internet page, colors appear yellowish in on the office monitor, they look too dark on the beamer of the colleague, dad's laptop alters the bright colors blueish and grandma's plasma display gives an overall pastel appearance.
This has to do with each monitor's adjustment, with the system used, with the image processing program, the browser, etc. This is how the Internet works at the moment and is exactly what we want to take advantage of. Our research group tries to use this circumstance to draw conclusions to quality estimations and employed standards. Normally, for such 'psycho-visual tests', people are invited to evaluate a bunch of images in a darkened, standardized room on expensive high-end displays. This is a very costly and time-consuming task which leads, amongst other things, to why the issue of color, particularly in computers, still is not solved to a common satisfaction. We are trying to create such tests more efficiently by having the user investigate images at home on his own computer.
For this, we are looking for volunteers who take part in this test; since the start last week about 150 people already took the test. It is simple and takes, depending on enthusiasm, ten to twenty minutes and has no side effects. The test is available in English, German and Polish, all information is stored anonymously. There is no right or wrong; we are simply trying to find out how the average Internet user evaluates images.
The research group of Empa's Media technology department and especially the project leader Iris Sprow would be glad if many ECI members would participate in the test; of course all others are encouraged as well, family, friends, etc.
