Building a Potassium MOT

A magneto-optical trap (MOT) was developed in order to cool and trap potassium atoms. This required construction of a mechanism for tuning and locking the frequency of a trap and repump laser in order to maintain the correct energy transitions needed to ensure trapping of the atoms. Once the lasers’ frequencies were locked, the beams were combined and amplified and can now be combined with lase...

SOT for MOT

In this paper we present a robust tracker to solve the multiple object tracking (MOT) problem, under the framework of tracking-by-detection. As the first contribution, we innovatively combine single object tracking (SOT) algorithms with multiple object tracking algorithms, and our results show that SOT is a general way to strongly reduce the number of false negatives, regardless of the quality ...

Système d'aide à l'accès lexical : trouver le mot qu'on a sur le bout de la langue

Le Mot sur le Bout de la Langue (Tip Of the Tongue en anglais), phénomène très étudié par les psycholinguistes, nous a amené nombre d’informations concernant l’organisation du lexique mental. Un locuteur en état de TOT reconnaît instantanément le mot recherché présenté dans une liste. Il en connaît le sens, la forme, les liens avec d’autres mots... Nous présentons ici une étude de développement...

KinFu MOT: KinectFusion with Moving Objects Tracking

Using a depth camera, the KinectFusion algorithm permits tracking the camera poses and building a dense 3D reconstruction of the environment simultaneously in real-time. We present an extension to this algorithm that allows additionally the concurrent tracking and reconstruction of several moving objects within the perceived environment. This is achieved through an expansion of the GPU processi...
