Problems involving recognition patterns in image, speech, or data arise in many different fields, including engineering, computer science, biology, medicine, operations research, management science, and the analysis and control of large systems.

Gaussian Scale-Space Theory in Copenhagen, in spring 1996. After this, Bart ter Haar Romeny arranged the First International Conference on Scale-Space Theory in Computer Vision (Utrecht, July 2-4, 1997). Indeed the title was ap- appropriate since this was the first scale-space conference in a series of so far two conferences. We feel very confident that the series will be much longer. We hope that the scheduling next to ICCV '99 will attract more delegates furthering the integration of scale-space theories into computer vision.
