    On the realism of digitally synthesized images



    The synthesis of continuous tone raster scan images has been the subject of considerable research effort over the past decade or so. Many algorithms have been developed during this period, and many significant advances have been made. Systems now exist which are capable of generating full color images of fairly complicated scenes, at rates high enough to support the illusion of smooth motion. Such systems have been commercially available for several years.

    Despite this glowing record, very few images have ever been produced which require more than a moment’s study to reveal their synthetic origins. The great majority of images produced are little more than caricatures. While such caricatures are good enough to be genuinely useful in applications ranging from geometric design to pilot training, the goal of producing images indistinguishable from those produced by conventional photography ought to be closer than is apparently the case.

    This presentation reviews the major issues of relevance to the realism of synthetic images. The major outstanding problems are identified and some suggestions for their solutions are presented.
