Xerox Corporation Webster, NY
Manager, Image Processing, IJBU
1997–2001
-
Leadership
of a multi-disciplined team of physicists, chemists, imaging,
electrical and print cartridge engineers responsible for the design
and development of the image path and imaging algorithms used in the
Xerox DocuPrint M Series and Sharp AJ series ink jet product lines.
-
Authored
the print engine image processing specification to enable smooth
translation of the imaging requirements to firmware vendors and
overseas partners.
-
Designed
and developed an image processing techniques making Xerox’s
DocuPrint M Series and Sharp AJ Series Ink Jet Products the fastest
printers in their class.
-
Designed
and implemented a manufacturing line quality inspection process
employing imaging methodologies and visual assessment techniques in
our partners overseas facility that reduced inspection time from 20
minutes per machine to one minute per machine.
-
Designed
and implemented custom imaging software tools, in Microsoft Visual
C++, to display, analyze, create and manipulate printer ready files
that enabled isolation and remediation of imaging defects within the
products.
-
Efficiently
and resourcefully solved 5 launch-critical image quality problems
where complex subsystem interaction and or machine to machine
variations obfuscated results.

Print Driver Development, Manager, IJBU
1996–1997
-
Increased
the quality, productivity and schedule predictability of Microsoft
Windows print driver development by fostering use of source code
configuration management, schedule management, problem management and
software quality control processes. Created an empowered and
professional work environment, which consistently delivered high
quality software on time over a span of 48 scheduled releases.
-
Responsible
for negotiating vendor deliverables, print driver release content and
schedule for all Windows Print Drivers for Xerox’s ink jet products
ensuring customer satisfaction of both internal and OEM customers.

Color and Imaging Science Senior Project
Engineer, ISE&T
1993-1995
-
Invented a color image
processing technique for trapping allowing for the reduction of color
plane registration tolerances and paper handling sub-system’s cost
reductions.
-
Developed a
psychophysical scale that measures the perception of graininess, or
image noise, in halftoned color images enabling a consistent
non-subjective measure of halftone graininess.
-
Analyzed market survey
data on customer perceptions of the graininess in halftoned images.
The analysis yielded an image quality specification for mid-volume
copier products.
-
Designed and developed
the halftone screen pattern used for the Document Centre System 20
that minimized imaging artifacts induced by the resolution enhancement
technology employed.

Color and Imaging Science Senior Project
Engineer, ISDL
1991-1993
-
Optimized, designed and
implemented color management parameters used within an experimental
PostScript level 1 and Interpress digital front end RIP resulting in a
higher level of image quality than previously seen and the sale of the
technology to Fuji Xerox where it was incorporated into a product with
approximately 500 field placements.
-
Investigated advanced
technologies such as Object Oriented Halftoning, gaining insight to
image quality artifacts associated with parameter selection in order
to give copying and printing products a technical edge.
-
Designed and conducted
experiments on the visual artifacts associated with the JPEG and the
Generalized Vector Truncation Coding (GVTC) Image Compression
techniques resulting in the selection of JPEG image compression to be
used as an intermediate image format in a printing system resulting in
significant cost savings.
-
Developed an insightful
methodology to analyze the instantaneous throughput of the JPEG
compression algorithm resulting in the reduction of the FIFO buffer
size requirements needed in hardware and the cost savings on
semi-conductor components.

Color and Imaging Science Project Engineer
1986-1991
-
Established a Color
Image Quality Measurement Laboratory. Maintained the calibration
of instrumentation to standards defined by the National Institute of
Standards and Technology. Managed three technicians training them and
other users on the usage of the instrumentation.
-
Optimized the color
image processing parameters used in the Xerox 5775 Digital Color
Copier by adjusting tone reproduction curves and digital filters as
well as investigating image noise sources within the scanner and image
processing modules resulting in higher image quality at product
launch.
-
Designed and developed
final production line manufacturing test patterns, which were used in
the outgoing inspection process of the Xerox 5775 Digital Color
Copier.
-
Developed image quality
measurement techniques for psychophysical measures of scattering and
color quality in overhead transparencies.
-
Determined the effects
on image quality of color toner contamination in the manufacturing
process and developed acceptable limits of cross contamination.
