Graph Clustering for Image Segmentation
We propose a graph clustering approach for image segmentation by developing diffusion processes defined on arbitrary graphs.
Audiovisual Speech Inversion
We focus on recovering aspects of vocal tract’s geometry and dynamics from speech, a problem referred to as speech inversion.
Image Texture Modeling and Analysis
We pursue a concise texture modeling, analysis and segmentation system for generic natural images.
Multigrid Geometric Active Contours
We investigate multigrid techniques for the solution of the time-dependent PDEs of geometric active contour models in Computer Vision.
Audiovisual Speech Recognition
We have developed highly adaptive multimodal fusion rules based on uncertainty compensation which are compatible with synchronous and asynchronous multimodal interaction architectures.
Movie Summarization
Detection of perceptually important video events is formulated on the basis of saliency models for the audio, visual and textual information conveyed in a video stream.
Digital Restoration of Missing Parts in the Theran Wall Paintings
We have been working on PDE and wavelet-based techniques for the digital restoration of missing parts in paintings.
Sign Language Recognition
We have developed a visual processing framework for hands and head tracking and feature extraction from SL/gesture videos.
