Odd multiway cut in directed acyclic graphs
… Our main contribution is a broadening of the shadow-removal framework to address parity problems in DAGs. We complement our FPT results with tight approximability as well as polyhedral results for 2 terminals in DAGs. Additionally, we show inapproximability results for odd multiway edge cut in …

Anisotropic variational models and PDEs for inverse imaging problems
… osmosis model introduces when applied to shadow removal in images. Last but not least, we explore applications of variational models and PDEs to cultural heritage conservation. We develop a new non-invasive technique that uses multi-modal imaging for detecting sub-superficial defects in …

Robust Video Object Tracking via Camera Self-calibration
… thresholds of background subtraction and shadow removal around the adaptive kernel regions based on the preliminary tracking results. With the head/foot points collected from tracking and segmentation results, mean shift clustering and Laplace linear regression are introduced in the …
