E ver since the establishment of cell theory in the early 19th century, which recognized the cell as the fundamental building unit of life, biologists have sought to explain the underlying principles. Momentous discoveries were made in the course of many decades of research [1], but the quest to attain full understanding of cellular mechanisms and how to manipulate them to improve health, conti...

Definition Zooming facilitates data presentation on limited screen real-estate by allowing the users to alter the scale of the viewport such that it shows a decreasing fraction of the information space with an increasing magnification. Hence the system may first present a global overview of the information space for the benefit of orientation, and in a second step, the users can then dynamicall...

Spatio-temporal knowledge representation often requires changing from one level of detail or granularity to another so users can carry out a desired task. Meteorological occurrences, geological processes, or population movements, for example, can be examined at different granularities. This includes different spatial perspectives as well as temporal views where phenomena may be examined under r...

This article presents a new system for estimating the direction of multiple speakers and zooming the sound of one of them at a time. The proposed system is a combination of two levels; namely, sound source direction estimation, and acoustic zooming. The sound source direction estimation uses the so-called energetic analysis method for estimating the direction of multiple speakers, whereas the a...

Jazz is a new general-purpose toolkit that supports applications using zooming object-oriented 2D graphics. It is built entirely in Java using Java2D, and thus runs on all platforms that support Java 2. It supports zooming, internal cameras, and lenses in a similar style to Pad++, but does so in a general purpose manner without a specific focus on zooming. Jazz is primarily a "scenegraph" for 2...

We are investigating a novel user interface paradigm based on zooming, in which users are presented with a zooming view of a huge planar information surface. We have developed a system called Pad++ to explore this approach. The implementation of Pad++ is related to real-time 3D graphics systems and to 2D windowing systems. However, the zooming nature of Pad++ requires new approaches to renderin...

The limited screen real estate of touchscreen devices necessitates the use of zooming operations for accessing graphical information such as maps. While these operations are intuitive for sighted individuals, they are difficult to perform for blind and visually-impaired (BVI) people using non-visual sensing with touchscreen-based interfaces. We address this vexing design issue by investigating ...

Image Fusion is the process in which core information from a set of component images is merged to form a single image, which is more informative and complete than the component input images in quality and appearance. This paper presents a fast and effective image fusion method for creating high quality fused images by merging component images. In the proposed method, the input image is broken d...

It is demonstrated that the pre-dual for problems with total bounded variation regularization terms can be expressed as bilaterally constrained optimization problem. Existence of a Lagrange multiplier and an optimality system are established. This allows to utilize efficient optimization methods developed for problems with box constraints in the context of bounded variation formulations. Here, ...

Computing system representations based on Harel's notion of hierarchical graph, or higraph, have become popular since the invention of Statecharts. Such hierarchical representations support a useful ltering operation, called \zooming-out", which is used to manage the level of detail presented to the user designing or reasoning about a large and complex system. In the framework of (lightweight) ...
