CSc I6732: Information Theory
with Applications to Satellite Image Processing
This course will deal, in increasingly detailed fashion as the
semester progresses, with concepts and methods that are involved in
appropriately defining and analyzing the information content of various
kinds of data. We will introduce and discuss concepts from Shannon's treatment of
information theory: the basic notions of entropy, relative entropy,
and mutual information, and show how they arise as natural answers to questions
of data compression, channel capacity, rate distortion and hypothesis
testing.
The subject of information, and various ways in which it can be
represented, is of course closely linked to the study of data compression.
As the semester progresses, we will increasingly stress the compression
aspects of the subject, and the course will conclude with a detailed study and
analysis of data representing observations of the Earth from space. Understanding
and predicting changes in Earth's environment is increasingly dependent
on the management of vast quantities of data. For example, the rich data
streams produced by next-generation instruments planned for upcoming
environmental satellites will need to be compressed and protected from the
inevitable presence of error introduced during transmission.
This is a subject of considerable practical importance, and one which
is currently being very actively pursued at the Cooperative Remote Sensing
Science and Technology Center
(CREST) of CCNY. It is expected that as
the course progresses, students who show signs of
demonstrated interest and
promise in this area may, at the instructor's discretion,
be eligible for
funding, which is available for the support of work in this area.
