Project Goals

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.

Project Goal

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 effectiveness.
