Teaching>EE 5263.002 Wavelets, Digital Watermarking and Steganography

Department of Electrical Engineering
EE 5263.002 Wavelets with Multimedia Applications (Credit 3)
Syllabus, Spring 2006

Catalog description: This course will provide an introduction to the wavelet transform theory and some associated applications. The wavelet transform has been perhaps the most exciting development in the last decade to bring together researchers in several different fields such as signal and image processing, communications, computer science, and mathematics. The wavelet transform expresses a given signal, image in terms of simpler signals built from a mother wavelet. The combination of exceptional theory, efficient algorithms, and successful applications makes the field of wavelets quite exciting.
Convergence originates with classical orthogonal representations and proceeds through wavelet decomposition. The topics include wavelet applications to

  • multimedia signal processing (multimedia signal enhancement, de-noising, compression)
  • multimedia security (watermarking, and steganography)

Steganography (literally "covered writing" in Greek) is the ancient art of hiding messages (mostly inside the physical object) so that they are not detectable. Throughout the centruies, many steganographic techniques have been developed. Modern steganography is a secure communication of information by embedding a secret-message within a "cover" digital multimedia without any perceptual distortion of the cover media, so the presence of the hidden message is indiscernible.
