Introduction and Motivation
Digital multimedia has changed the way we view computers.
For example, the emergence of digital multimedia has brought
DVD players to our home theaters, transformed our computers
into media centers, and has allowed us to take our media with
us in our handheld devices. Our project aims to examine one
of the technologies that have been key to this digital revolution,
digital video compression.
The most recognizable consumer application is DVD video.
On a DVD disc a movie is stored digitally as a string of ones
and zeros. Video compression algorithms, such as MPEG, use
various signal processing and video processing techniques
to reduce the storage space needed to represent a movie while
maintaining the highest quality possible.

In search of a better solution, we have created a video compression
algorithm that has many advantages over today’s mainstream
formats. The key is ‘Wavelets’. Most current video compression
techniques rely on the Discrete Cosine Transform (DCT). By
dropping the DCT and using the Discrete Wavelet Transform
(DWT), we have been able to produce a better video compression
system. Our project aims to explore the use of wavelets for
video compression. On this website, you will be shown some
basic video processing theory, how we used these ideas to
build the Wavegen Codec, and some test results to show its
