Semi-Regular Triangle Remeshing: A Comprehensive Study
2016
International audience; Semi-regular triangle remeshing algorithms convert irregular surface meshes into semi-regular ones. Especially in the field of computer graphics, semi-regularity is an interesting property because it makes meshes highly suitable for multiresolution analysis. In this paper, we survey the numerous remeshing algorithms that have been developed over the past two decades. We propose different classifications to give new and comprehensible insights into both existing methods and issues. We describe how considerable obstacles have already been overcome, and discuss promising perspectives.

Filter array-based spectral imaging - design choices and practical realization
2014
International audience; This talk discusses the practical difficulties encountered in the practical implementation of MSFAs imaging systems in 2014. We provide hints and solutions on several problems. We provide means of evaluation and criticise them. Although, we present recent results obtain at the University of Bourgogne.

Arrhythmia due to mild therapeutic hypothermia - a study in vitro
2013
International audience; Introduction: In case of resuscitation after CA, the brain suffers the ischemia and the inflammation from reperfusion. To days, the only therapy available is the mild therapeutic hypothermia (MTH) : put the patient under 34°C-32°C during 12-24 hours. MTH has been shown to increase the hospital survival rate, but it has many adverse effects, among which the cardiac arrhythmia generation represents an important part (up to 34%). Cardiac culture in vitro provides a better spatial resolution than study in vivo, which could bring some insights of the mechanism of post-hypothermia arrhythmia generation. Method: Monolayer cardiac culture is prepared with cardiomyocytes from…
An open system to generate hyperspectral cubes for skin optical reflectance analysis
2010
International audience; Optical visible light analysis of the skin mainly relies on RGB colour imaging. Multispectral imaging of human skin represents a more accurate approach for in vivo analysis of its optical properties. Few dermatology-oriented multispectral devices have been hitherto developed. Their diagnostic abilities for pigmentary tumors or other clinical applications are still being evaluated [1]. We have developed a multispectral imaging system for in-vivo skin optical analysis. It is based on a charge-coupled device camera, a rotating wheel with a set of seven interference filters and a computer. All interference filters were chosen specifically to cover the visible spectrum ra…
