organized by Bertram Düring (University of Sussex), Carola-Bibiane Schönlieb (University of Cambridge)

We present an anisotropic extension of the isotropic osmosis model introduced by Weickert et al. (2013) for visual computing applications. Our model minimises an energy which involves a suitable quadratic form where the local directionality of the imaging structure is considered. Our anisotropic approach applied to shadow removal applications outperforms the isotropic one since it does not suffer from blurring artefacts at the shadow boundaries.},

abstract = {This presentation is part of Minisymposium “MS26 – New trends in inpainting”
organized by: Yann Gousseau (Telecom ParisTech) , Simon Masnou (Université Lyon 1) .

The talk will be devoted to a new class of higher-order anisotropic total variation regularizers, with applications to image denoising and to digital elevation maps reconstruction. Our model can mix isotropic and anisotropic regularization at various derivative orders, which helps recovering the intrinsic structure of images and surfaces. I will describe a primal-dual approach for the numerical implementation of the model. The talk will be illustrated with various numerical examples.},

abstract = {This presentation is part of Minisymposium “MS15 – Nonlinear Diffusion: Models, Extensions and Algorithms (2 parts)”
organized by: Ke Chen (University of Liverpool) , Joachim Weickert (Saarland University) , Xue-Cheng Tai (Hong Kong Baptist University) .

We introduce a generalized image osmosis model, enhancing the quality of the reconstructed image in the shadow removal problem by means of directional diffusion weights. Analogies with the second order linear and nonlinear diffusion inpainting equations (e.g. Harmonic, AMLE, Total Variation) acting on the shadow boundaries are further shown. Numerical details of efficient implementations for the model are provided, as well as applications to real images and to cultural heritage conservation challenges.},

Session Title: Challenges from End-Users

Ancient pots are generally classified by shape, represented as a profile (section): similar profiles are assumed to be related (e.g. functionally, if not chronologically). Commonware pottery is the most widely found class of material culture at Roman sites, yet its enormous range of shapes is such that its classification is at least 10-20 times more laborious than other classes (fineware, amphorae). However, important development in the field of computer-aided image analysis might provide archaeologists with a set of automated form recognition tools to help them during their classification process. },
