Dear Faculty and Students,
I am pleased to announce our first Spring 2012 Junior Colloquium.
Speaker: Dr. Amy F. Szczepanski, University of Tennessee, Electrical
Engineering and Computer Science
Title: Understanding the Encoding of JPEG Images
Abstract: JPEG encoding allows large images to be represented as fairly
small files.
This compression is achieved through clever use of algorithms that take
advantage of the fact that pixel intensity and color both tend to change
fairly gradually throughout an image.
We'll see how this property, together with well-chosen matrices
and smart ways of representing long strings of zeros, allows the JPEG
format to encode images efficiently. This talk should be accessible to
anyone who is comfortable with matrix multiplication.
Place: Fourth Floor Colloquium Room, Ayres
Hall.
Time: 3:35 pm.
Date: Thursday January 19 2012
The customary pizza will be served at 3:15.
Wish you all a wonderful 2012.
Stella Thistlethwaite
