Paper Abstract

One of the image quality problems with printing images from the WEB is that the color information associated with those images is normally incomplete, or even incorrect. In order to generate a good printout of an arbitrary image from the WEB, certain assumptions have to be made. The major variant in image quality can be found in terms of the intended (gamma) the image was designed for. The example is a WEBsite, hosting an image collection. The site might allow you to browse and print images. However, browsing is normally done on a monitor with a (gamma) of roughly 2 and printing is done on a xerographic or ink-jet printer with a (gamma) of 1. The display and print images will therefore differ quite drastically, unless the (gamma) is corrected. Unfortunately, it is not known which (gamma) setting was used by the WEBsite, and therefore a fixed conversion (e.g.: always assuming the data is intended for monitor (gamma) ) is often faulty. This talk describes a way around this problem by trying to automatically identify the correct (gamma) based on the image data.
