Management of Images Collections

The proliferation of handled devices combined to telecommunication and information technology allows to manage visual documents from everywhere at any time. The management methodologies need to take into account different factors and constraints such as battery life, processing capacity, communication costs, user specificity, and user context. In our talk we will focus on content based visual document suggestion (CBIS). An unified statistical model for the user need, his/her context, and the visual document collection will be presented. The suggestion is based on Bayesian reasoning such as the estimation of mixtures of Dirichlet pdfs. A mixture of Dirichlet pdfs have nice properties for modeling a non-Gaussian data in high dimensional space. Several experimental results will be shown.
