Media Security & Watermarking
Description:
In the area of media encryption we are specializing in lightweight and partial encryption schemes for image and video data
with special emphasis on scalable media like JPEG2000 or H.264 SVC. In the watermarking area our focus is on
developing key-dependency schemes for robust embedding techniques. Scalable watermarking and multiple watermarking are recent topics
of reasearch. In robust hashing, key-dependent wavelet transforms are investigated as a means to provide security for such
schemes.

Image- and Videocoding
Description:
We have been specializing in image and video compression techniques involving wavelets for over 10 years now.
Emphasis has been given to adaptive techniques like wavelet packets or object based coding inspired by MPEG-4.
Also, cache efficient and parallel algorithms have been developed for a number of corresponding algorithms. More recently,
we concentrate on scalable coding schemes like JPEG2000, MCTF scalable wavelet codecs, and H.264 SVC.
Funded Projects:
Biometrics
Description:
We focus on biometric modalities where image processing is conducted during feature extraction and
template generation (i.e. fingerprints, iris, face, retina, hand and foot geometry). Current emphasis of our work
is on hand- and footgeometry,
on sample data compression and encryption, as well as on privacy in biometrics (like cancelable biometrics).
Funded Projects:
Medical Image Classification
Description:
Together with partners from different medical departments, we apply classification techniques to medical image data
targeted towards the development of computer-based decision support systems for endoscopic imagery. On the one hand,
classical texture classification features are used, on the other hand we develop new schemes and customize them to the
target imagery. Currently, we work on a staging technique for colon cancer and diagnosis of celiac disease.
