Feedback on a publicly distributed image database: the messidor database
Etienne Decencière,Xiwei Zhang,Guy Cazuguel,Bruno Lay,Béatrice Cochener,Caroline Trone,Philippe Gain,John-Richard Ordóñez-Varela,Pascale Massin,Ali Erginay,Béatrice Charton,J.-C. Klein +11 more
TL;DR: The feedback on the Messidor database, after more than 6 years of diffusion, is analyzed and the real interest and benefit of the research community is not easy to quantify.
Journal ArticleDOI
TeleOphta: Machine learning and image processing methods for teleophthalmology
Etienne Decencière,Guy Cazuguel,Guy Cazuguel,Xiwei Zhang,Guillaume Thibault,J.-C. Klein,Fernand Meyer,Beatriz Marcotegui,Gwenole Quellec,Mathieu Lamard,Ronan Danno,D. Elie,Pascale Massin,Z. Viktor,Ali Erginay,B. Laÿ,Agnès Chabouis +16 more
TL;DR: In this paper, a complete prototype for the automatic detection of normal examinations on a teleophthalmology network for diabetic retinopathy screening is presented, which combines pathological pattern mining methods, with specific lesion detection methods, to extract information from the images.

Journal ArticleDOI
Exudate detection in color retinal images for mass screening of diabetic retinopathy
Xiwei Zhang,Guillaume Thibault,Etienne Decencière,Beatriz Marcotegui,Bruno Lay,Ronan Danno,Guy Cazuguel,Gwenole Quellec,Mathieu Lamard,Pascale Massin,Agnès Chabouis,Zeynep Victor,Ali Erginay +12 more
TL;DR: New preprocessing methods are proposed, which perform not only normalization and denoising tasks, but also detect reflections and artifacts in the image, and a random forest algorithm is used to detect the exudates among the candidates.
Journal ArticleDOI
Single-dose toxicokinetics of aluminum in the rat
TL;DR: Al toxicokinetics was dose dependent and appeared to plateau at 12000 μg/kg and in no case was fecal elimination of incorporated Al observed.
