My research subject is computer vision and more broadly sensing visual
information. Visual information is central to a growing number of
applications from monitoring the earth's environment from satellites, to
uncovering the structure of the brain with MRI. My focus is to use
physically accurate models of the sensing process to better interpret and
manipulate visual information. For example, by modeling the sensor it
should
be possible to develop better compression methods. Besides simply modeling
sensors, I am investigating improved sensing strategies and sensor design,
including using active illumination such as projectors. Visual sensing can
also be greatly in enhanced with multi-modal data through sensor fusion. I
am pursuing projects along these themes with applications to remote
sensing,
medical imaging, computational vision, computer graphics and the human
computer interface.

A main focus of my research is to improve access to information on the
World Wide Web, by developing methods for enhancing the automatic search
process and presenting more useful search results to the user. I am
currently
extending and refining a developed meta-search engine as a research tool
in the design and development of improved methods of capturing, filtering,
organizing, and presenting search results. My other research interests
center
around the area of database and transaction processing systems.

My main research interest is in Distributed Computing, including
synchronization algorithms, petri nets, distributed simulation,
termination detection, distributed graph algorithms, and correctness
proofs.
I am also interested in Computer Science Education, including semiformal
program specification and verification, effective ways of communicating
computer science concepts.

My research interests are in the fields of speech and natural language
processing and spoken dialog systems. Currently I am involved in several
research directions: learning from interactions for spoken dialog systems;
user adaptation to spoken dialog systems; computation of word sense
frequencies using latent semantic analysis; automating voice interface to
large directories; and named entity extraction.
Dan McCracken
My research interest is in Human-Computer Interaction as applied to
website design in my course CSc 473, Website Design. My book
User-Centered Web Site Design: A Human-Computer Interaction Approach
was published by Prentice-Hall in 2004 My coauthor was Dr. Rosalee
Wolfe of DePaul University, a pioneer in HCI education. (This was my
25th book.) I am currently involved in deepening my knowledge of all
aspects of Java, which I teach regularly in CSc 221, Software Design
Lab, and which I will be teaching in Spring 2006 in CSc 59937,
Advanced Java.

My research interests lie in the broad area of organizational and
managerial
issues in computing. In recent years my attention has focused on: 1)
virtual
organization, 2) information commodities, and 3) search engine
performance.
First conceived in the late 1970s as an analogy between practices of
multinational firms and the management of virtual memory, virtual
organization
has been a preoccupation ever since. Currently examining the advantages
and
limitations of this management paradigm by studying the costs of
"switching"
in practice. The switching model of virtual organization is based on a
logical separation of the requirements of a task from the means for
satisfying
them. Switching itself refers to the re-assignment of satisfiers to
requirements. My interest in information commodities is linked to virtual
organization, since the replacement of human knowledge and skill by
computer programs and databases is essential to the practical realization
of switching. Outsourcing, an example of an existing management practice
that can be used in switching, is greatly facilitated by the ability to
obtain "packaged" knowledge and skill. The third area - search engine
performance - harks back to a long-standing concern with social issues
in computing. My interest here is in analyzing popular search engines for
signs of bias in the retrieval and presentation of information.
Janos Pach
I do research in discrete and computational geometry and combinatorics,
and published two monographs and cca. 150 research papers in these fields.
I am particularly interested in questions related to the combinatorial
complexity of various geometric objects, which have applications in
robotics
(motion planning) and computer graphics. I serve on the editorial boards
of
five professional journals (Discrete and Computational Geometry,
Combinatorica,
Graphs and Combinatorics, Computational Geometry, Geombinatorics), and won
the
L. R. Ford Award (Math. Assoc. Amer.) and the Renyi Prize (Hungar. Acad.
Sc.).

I currently pursue multi-pronged research activities in the areas of
distributed & parallel systems, multi-service networks, multimedia
information systems, and internet-based communication architectures.
My major works have been in the directions of "dataflow"-style programming
models for distributed embedded systems, concurrency control mechanisms
for distributed collaborative settings, application-level programmability
of core system functionalities, end-system mechanisms for QOS-adaptive
communications over "best-effort" Internet, verifiable design of
distributed
protocols & programs, and predicate-monitoring based systems & network
management.

My present work has as its main goal the understanding of methods by
which algebraic manipulations of indefinite objects can be automated.
If successful, this work will point the way to achieving a new level
of abstraction in symbolic computation. Towards this end, I am
building stream- and continuation- based software tools
for addressing a variety of problems concerning parametrized families
of finitely presented groups, and a system for manipulating indefinites.
This work is supported by an NSF grant, under the auspices of the Center
for Algorithms and Interactive Scientific Software of City College, and
is joint with Gilbert Baumslag, and Professors Sean Cleary and William Sit
of the Department of Mathematics.

My research interests are in the area of computerized typesetting,
expanding on related areas. Over the years my work included multi-target
multi-platform extended TeX compiler (VTeX), issues of interaction between
text formatting and graphics (GeX), mathematical font design, design and
support of multiple master fonts in typesetting software, and, most
recently, work on a fully WYSIWYG typesetting system based on LaTeX
formatting algorithms (microIMP).
Jie Wei
My research is centered around two topics in computer vision: active
sensing
and visual information reconstruction. 1) within the framework of active
sensing, based on animate vision system, I have been researching efficient
and effective methods to make cameras participate in the sensing process
by
actively adjusting their optical parameters and geometrical locations to
better sense and explore the world. 2) To reconstruct visual information
from images and videos, the issues I deal with include a) still image
segmentation which partitions images into regions of coherent colors and
textures; b) motion estimation and segmentation which attempts to recover
the motion information from videos and single out objects based on
coherent
motion; c) color constancy techniques which are employed to discount the
variations of lighting conditions to represent and recognize objects in
digital libraries.

Wolberg
My research interests lie in the areas of image processing, computer
graphics, and computer vision. Some of my recent research work has
addressed the following problems: 3D photography for importing high
resolution 3D models of existing large-scale urban scenes, automatic
image registration (alignment) of digital images, 3D registration of
laser range scans, monotonic cubic spline interpolation, a general
framework for morphing among multiple input images, image morphing
from scattered feature constraints, scattered data interpolation using
multilevel B-splines, and restoration of images scanned in the the
presence of vibrations. I am one of the early pioneers in the area
of image morphing, a powerful visual effects tool in film and television
depicting the fluid transformation of one digital image into another.
This work is documented in my book "Digital Image Warping", the first
comprehensive book on warping and morphing.
