Abstract: A method (30) and system (10) for controlling wireless local area network (WLAN) user quality in a multi-access point environment is provided. In order to ensure good quality of service/user experience in a multi-access point Wi-Fi™ setup in which a user roams with a station (14), the access points (11, 12) continuously or at intervals assess the wireless environment's quality and report to a control entity (13). The control entity (13) determines, from the assessment data, alternative target access points (11, 12) that could be used in case the link quality of a current connection between an access point (11) and the station (14) falls below a pre-defined value. The control entity (13) then instructs the access point (11) to actively disconnect the station (14) and selects a new target access point (12) to accept the stations (14) connection request.

Abstract: In image segmentation it is usually assumed that all the surfaces of a scene are reflecting light in a perfectly diffuse or Lambertian manner. However, most existing surfaces are non-Lambertian surfaces. Examples of non-Lambertian surfaces are specular, glossy or mirror-like surfaces whose appearance may change depending on the point of view of the scene. The method according to an embodiment of the invention does not make the assumption that surfaces of objects in the view are perfect Lambertian reflectors by providing a surface color segmentation which takes into account the change in appearance due to the nature of the surfaces.

Abstract: A query-set is used to obtain recommendation results from different recommendation algorithms available locally on a device. The same query-set is used to obtain recommendation results from a remote, well-established online recommendation system using an unknown recommendation algorithm.

Abstract: The present disclosure relates to methods, apparatus or systems for determining an aiming direction (22) of a remote motorized camera (10). The immersive video content captured by the camera (10) is associated with reference directions (13). Parameters of a discrepancy function (32, 42, 53) are calculated. This function is used to control the aiming direction (22) of the camera. It introduces a discrepancy between the rotation wanted by the user (21) and the rotation of the camera (22). An example purpose of the present disclosure is to encourage a user to rotate the camera toward reference directions, preventing him/her to rotate the camera toward the opposite direction. The present principles have the advantage to create pseudo-haptic effects, inciting the user to look toward a reference direction without making him/her sick.
