Welcome to the website of the Signal Compression Lab (SCL). A constituent of the Department of Electrical and Computer Engineering (ECE) at the University of California, Santa Barbara (UCSB), we are located at 3166, Harold Frank Hall, on the beautiful oceanfront of the campus.

Our research covers a wide spectrum of topics in signal compression and related areas, and is a confluence of both theoretical foundations, and practical algorithms and applications. Multimedia compression and networking, in particular audio and video coding, and     transmission, estimation theory, distributed source coding, pattern recognition and classification, indexing and retrieval from databases, and bio-informatics, are some of our current research emphases. Follow the various links at the top of this page for more information on our research activities and people involved.
