Ingénierie, climatologie et topographie de l'être-dans-le-monde – Des îles pour penser l'architecture?

This text is an architect's reading of the last volume of Peter Sloterdijk's trilogy Ecumes (Foam), particularly the two chapters “Insulations” and “Indoors”. It raises the issue whether the atmospheric analysis that Sloterdijk develops from his representation of the being-in-the-world and the inhabitation can lead to a new understanding of space that would help reach more habitable future spaces. It suggests that the metaphor of the island can help construct some sort of an intermediary analysis and conception object: the (new) machine-to-live-in. Through the exercise of the atmospheric analysis, it suggests a new critical reading of the conception processes of human spatiality, which gives a glimpse into the possibility of setting new generators for contemporary space design.</p

Computer-Assisted Segmentation of Videocapsule Images Using Alpha-Divergence-Based Active Contour in the Framework of Intestinal Pathologies Detection

Visualization of the entire length of the gastrointestinal tract through natural orifices is a challenge for endoscopists. Videoendoscopy is currently the “gold standard” technique for diagnosis of different pathologies of the intestinal tract. Wireless Capsule Endoscopy (WCE) has been developed in the 1990's as an alternative to videoendoscopy to allow direct examination of the gastrointestinal tract without any need for sedation. Nevertheless, the systematic post-examination by the specialist of the 50,000 (for the small bowel) to 150,000 images (for the colon) of a complete acquisition using WCE remains time-consuming and challenging due to the poor quality of WCE images. In this article, a semiautomatic segmentation for analysis of WCE images is proposed. Based on active contour segmentation, the proposed method introduces alpha-divergences, a flexible statistical similarity measure that gives a real flexibility to different types of gastrointestinal pathologies. Results of segmentation using the proposed approach are shown on different types of real-case examinations, from (multi-) polyp(s) segmentation, to radiation enteritis delineation
