Abstract
:

Due to the projected increase in the type 2

diabetes epidemic,
there is a critical need for
widely available

and inexpensive screening for diabetic retinopathy, a

preventable
secondary disease caused by diabetes that can lead

to decreased visual function and even
blindness. Currently this

type of testing can only be p
erformed manually by trained

ophthalmologists, but a telemedicine network with retina

cameras and automated quality
control, physiological feature

location, and lesion / anomaly detection is a more cost
effective

method of providing broad
-
based screening.
In this paper we

report on the method
of using Hierarchical Temporal

M
emories (HTMs), a new type of machine learning
technology

based on the function of the human neocortex, to locate optic

nerves as an
alternative method for physiological feature

location

as a part of the larger telemedicine
network scheme.

We compare the results from the HTM network on a data set

collected
from a Memphis, TN clinic to the results from more

conventional machine vision techniques.
We show that while

HTM technology as it is
used with this procedure is not as

accurate as
traditional image analysis and processing methods,

it is still quite effective and is a
promising new technology for

machine vision applications such as the diabetic retinopathy

telemedicine network.


Biographical Sketch:


Aidan R. W. Boone was born in Virginia, but has lived most of his life in Tennessee.
In 2008 he graduated from Farragut High School
, and he is c
urrently a rising j
unior at
Vanderbilt University earning his
bachelor’s degree

in the Bio
medical Engineering
Department.

Since

2007, while a

high school

senior,

he has been participating in research projects
at Oak Ridge National Laboratory.
He initially did some genetics research involving diabetes
an
d adipocytes, then returned to do summer
work in the Image Science and Machine Vision
group

working on automated diagnosis of diabetic retinopathy.
He has been working this
past spring in the biomaterials lab at Vanderbilt University,
and

remains interested in
the
medical
applications of
Hierarch
