Graph Clustering for Image Segmentation
We propose a graph clustering approach for image segmentation by developing diffusion processes defined on arbitrary graphs.
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.
Image Saliency through Spatial Surprise
Using an information-theoretic approach to study bottom-up spatial saliency, we show how Bayesian surprise can be interpreted to explain spatial saliency.
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.
