SIVA - The Signal, Image and Video Audiovisual Demonstration Gallery is a collection of teaching tools that facilitate a gentle introduction to concepts in signal and image processing. Equipped with informative visualizations and a user-friendly interface, SIVA uses novel LabVIEW and MATLAB based demonstrations to illustrate the power and beauty of signal and image processing algorithms. Most demos use audio and image signals to give students a flavor of real-world applications of signal and image processing. 

The SIVA demonstration gallery is used at 650+ academic, industrial and other sites around the world (57 countries).SIVA was published in the IEEE Transactions on Education:

Details about SIVA also appear as book chapters in the Handbook of Image and Video Processing and The Essential Guide to Image Processing. SIVA was also recently cited in the prestigious IEEE Signal Processing Magazine and the Proceedings of the IEEE.
