Dr. Andrew Willis receives the John H. Maxheim Faculty Fellowship
The William States Lee College of Engineering
Each year one tenure-track assistant faculty member within The William States Lee College of Engineering is selected to receive this award. Dr. Willis is honored for such recognition and support from both The John H. Maxheim Fellowship and the college which makes ongoing research within Charlotte Machine Vision Lab possible.
The John H. Maxheim Faculty Fellowship recognizes and promotes the career
development of tenure-track junior faculty in The William States Lee College
of Engineering. The quality of the academic programs provided by
the college is dependent on the talent and abilities of its faculty.
The John H. Maxheim Fellowship assists junior faculty with their development
and growth as educators and scholars. The grant associated with this fellowship
will be used to support and enhance the professional activities of the
recipient.
Eligibility
Tenure-track Assistant Professors with demonstrated accomplishments and
the potential for future impact on the college's programs are eligible
for the John H. Maxheim Faculty Fellowship.
Selection Process
The Maxheim Fellow will be selected on a competitive basis from the eligible
faculty. Contributions to the programs of the college and the promise
for continued enhancement of these programs will be central to the award.
Eligible faculty will be reviewed by the department Chairs in consultation
with the Dean. Eligible faculty will be reviewed by the department Chairs in consultation
with the Dean. Selection will target each department on a rotating basis.
Priority will be given to nominees of the primary department and the Chairs
will present the accomplishments of the eligible faculty for evaluation,
discussion, and selection by the committee.
The Maxheim Fellow will be announced by the Dean the last week of February
of each year, at which time the $5000 grant will be awarded. Subsequently,
the recipient will be recognized with a plaque or certificate at The William
States Lee College of Engineering Awards Luncheon in the spring. |

In this paper, we present a new technique for solving the difficult
problem of estimating the axis of symmetry for axially-symmetric
surfaces. Accurate solutions to this problem are important in
archaeology for systems that seek to reconstruct pottery vessels from
measurements of their fragments. Our approach estimates quadratic
surfaces at each measured surface point and uses a Markov Random Field
superimposed on the measured surface mesh to estimate a collection of
surface patches, each of which lies close to a single 3D quadratic
surface. For each surface patch we estimate an quadratic implicit
polynomial whose coefficients directly provide an estimate of the
unknown axis location and orientation. Competing estimates of the
global axis are combined using a Maximum Likelihood Estimation (MLE)
framework that reflects the uncertainty present in the estimates
computed from each surface patch. Our approach differs from past
approaches by combining estimates derived from large surface regions
that include many measurements instead of combining many local (often
pointwise) estimates of the surface to determine the global estimate.
Estimates from these large regions are more robust to noise and have
sufficient data to generate statistics that accurately reflect the
uncertainty in the computed estimates. As such, each estimate of the
central axis is less susceptible to outliers and the overall axis
estimate is significantly improved.
