Existing computer technologies poorly support the ideation phase common to graphic design practice. Finding and indexing visual material to assist the process of ideation often falls on the designer, leading to user experiences that are less than ideal. To inform development of computer systems to assist graphic designers in the ideation phase of the design process, we conducted interviews with...

This paper studies the problem of lossless compression of computer generated compound images that contain not only photographic images but also text and graphic images. We present a simple backward adaptive classification scheme to separate the image source into three classes: smooth regions, text regions and image regions. Different probability models are assigned within each class to maximize...

This paper describes a robust method for recognizing vehicle classes. In our previous work, we have developed a vehicle recognition system based on local-feature configuration, which is a generalization of the eigen-window method. This system could recognize one vehicle class very accurately, but there have been limitations in recognizing several classes, when they are quite similar to each oth...

As computer graphics (CG) is getting more photorealistic, for the purpose of image authentication, it becomes increasingly important to construct a detector for classifying photographic images (PIM) and photorealistic computer graphics (PRCG). To this end, we propose that photographic images contain natural-imaging quality (NIQ) and natural-scene quality (NSQ). NIQ is due to the imaging process...

Autostereograms or SIRDS (Single Image Random-Dot Stereograms) are camou aged stereograms which combine the Julesz random-dot stereogram principle with the wallpaper e ect. They can represent any 3d shape on a single image having a quasiperiodic appearance. Rather large SIRDS can be interpreted in depth with unaided eyes. In the hands of computer graphic designers, SIRDS spread all over the wor...

The goal of the National Computer Graphics Association is "to increase the productivity of industry and management in the United States through the use of computer graphics." The first four articles in this special issue, based on papers presented at NCGA '82 last June, reflect the association's continuing commitment to that goal. At the same time, they reflect an awareness-intensified since NC...

XCRIBL is a system developed at CMU for generating hard copy computer output of arbitrary type fonts, graphics, and grey-scale images using a Xerox Graphic Printer (XGP). XCRIBL can be used to generate documents approaching the quality of printed text with the use of a document generation language (XOFF or PUB) and a character set design program (BILOS). Textual and graphic information to be pr...
