Major Research Activities

One of our main research goals has been the development of computational techniques for the detection of digital tampering. This work has three main directions:

1. detecting the presence of hidden messages (steganography)

2. detecting traces of digital manipulation that change the content/meaning of an image (e.g., the ``gluing'' together of two photographs)

3. digital art authentication

We are also actively involved in several other areas of research:

1. Virtual Reality and Architecture: we developed computational tools for reconstructing ancient and modern architectural monuments.

2. Medical Imaging: we are working on medical image registration, mapping neural pathways using diffusion tensor MRI, and early detection of disease using fMRI.

3. Neural Binding: we are working to understand the hotly debated topic of binding by temporal synchrony.

4. Landscape Topography: we are developing computational tools for the automatic extraction of landscape topography from photographs.
