This thesis describes the study and implementation of a component for structural recognition of handwritten or typesetted mathematical formulae. This work is related to document analysis and recognition fields of research. Our aim could be resumed as : how to recognize the mathematical notation, i.e. the abstract syntax tree of a formula, just...

This paper describes current results of Ofr (Optical Formula Recognition), a system for extracting and understanding mathematical expressions in documents. Such a tool could be really useful to be able to re-use knowledge in scientific books which are not available in electronic form. We currently also study use of this system for direct input...

This paper describes the design and the first steps of implementation of Ofr (Optical Formula Recognition), a system for extracting and understanding mathematical expressions in printed documents. Our approach clearly separate OCR step, geometrical treatments and syntactic analysis. In this paper we focus on the third part: we define a class of...

This paper targets with applications running on mobile devices and using context informations. Following previous studies from other authors, we extend the notion of context area replacing distance function by cost function. Using this extension, we exhibit three different modes of selection and demonstrate their differences on a mobile...

Today, a growing amount of physical objects in our surroundings are connected to the Internet and provide the digital world with an interface to the physical world through sensors and actuators. At the heart of this trend, smart-* systems and applications leverage this interface to smartly and seamlessly assist individuals in their everyday...

This paper targets with applications running on mobile devices. We aim at developing a formalism and a framework to simplify the development of applications taking into account the context in which they are running, whatever this context may be. Following previous studies from other authors, we extend the notion of context area using distance...
