]]> We present knowIT, a collaborative database designed to manage the shared knowledge about Informatics Systems in a research organization. In this paper, we discuss requirements that emerged through years of use and we describe the challenges of migrating content from an existing relational database to a solution based on a Semantic MediaWiki. Finally, we review which customizations were required in order to improve user acceptance, both for editors and viewers. Our experience will serve as a case study for a pragmatic approach to knowledge management.

]]> Abstract

An in-house similarity searching system, PRISM (PRI Similarity Miner), has
been developed for the general purpose of lead identification for drug discovery.
Its algorithm is based on the fusion of 2D linear fragment descriptors of
different sizes, which reflect different degrees of fuzziness. The details of this
algorithm will be explained. Some validation results, using the NCI AIDS and
MDDR data sets, will be presented. We will also discuss application of this
method to fast HTS follow-up.

]]> Abstract

A possible definition for Computer Vision is the automatic inference of decisions from pictures with the help of computers. In this context, extracting one or many representations from the image of a scene plays a fundamental role.

Human Vision shows the existence of numerous mechanisms, the purpose of which is to continuously guide perception through the constant low of visual information. At a psychological level, more difficult to express in computational terms, one possible contribution to Computer Vision comes from Perceptual Grouping.

The work described in this manuscript uses the perspective of perceptual grouping to structure images into significant visual elements. We propose a progressive approach to extract visually important features from the contours of an image and give useful elements of representation of the scene for a higher recognition process.

We finally show how these visual elements can be used for the detection and matching of junctions between two images. Various results on synthetic and real images confirm the relevance of our approach.
