Paper Abstract

As the number of consumer digital images escalates by tens of billions each year, an increasing proportion of these images are being acquired using the latest generations of sophisticated mobile devices. The characteristics of the cameras embedded in these devices now yield image-quality outcomes that approach those of the parallel generations of conventional digital cameras, and all aspects of the management and optimization of these vast new image-populations become of utmost importance in providing ultimate consumer satisfaction. However this satisfaction is still limited by the fact that a substantial proportion of all images are perceived to have inadequate image quality, and a lesser proportion of these to be completely unacceptable (for sharing, archiving, printing, etc). In past years at this same conference, the author has described various aspects of a consumer digital-image interface based entirely on an intuitive image-choice-only operation. Demonstrations have been given of this facility in operation, essentially allowing criticalpath navigation through approximately a million possible image-quality states within a matter of seconds. This was made possible by the definition of a set of orthogonal image vectors, and defining all excursions in terms of a fixed linear visual-pixel model, independent of the image attribute. During recent months this methodology has been extended to yield specific user-interactive image-quality solutions in the form of custom software, which at less than 100kb is readily embedded in the latest generations of unlocked portable devices. This has also necessitated the design of new user-interfaces and controls, as well as streamlined and more intuitive versions of the user quality-choice hierarchy. The technical challenges and details will be described for these modified versions of the enhancement methodology, and initial practical experience with typical images will be described.
