International audience; A way to improve the early detection of colorectal cancer is screening. Polyps are a marker of colorectal cancer and the best modality to detect them is the image. In 2003 Wireless Capsule Endoscopy was introduced and opened a way to integrate automatic image processing to realize a screening tool. Moreover, the capacity to detect polyp with Convolutional Neural Network was shown in many scientific studies, but one issue is the integration of these networks. In this article, we present our works to integrate CNN or image processing based on a CNN inside a WCE to realize a powerful screening tool. We apply the knowledge distillation method. We prove that knowledge distillation is efficient from VGG16 to Squeezenet in polyp detection context

In today’s society, the use of watch-based technology is growing steadily and is being used in a wide range of applications and on different aspects of the user’s life, from sport and fitness measurement, to entertainment and healthcare evaluation. Considering the multiple application fields for smartwatch/wristbands and their potential adoption in precision medicine applications, it is thus critical to investigate the performance and accuracy of these devices in different potential scenarios of interest. textbfThis study investigated the performance and accuracy of a variety of commercially available activity trackers as regards the estimation of stepcount, distance, and heart rate in a number of walking/household/sedentary activities typical in everyday life, and recreated in a lab-environment in a study population of young adults. Results show that heart rate and stepcount measurements are accurate but unstandardized activities, such as common domestic or leisure tasks, may cause large errors in some devices. Finally, travelled distance can also represent a quantification challenge when climbing up/downstairs. This preliminary work will support the next phase of the project whose goal is to evaluate elderly subjects in lab- and freeliving environments in an ambient assisted living context.
