Abstract: A method for rendering a non-photorealistic (NPR) content from a set (SI) of at least one image of a same scene is provided. The set of images (SI) is associated with a depth image comprising a set of regions. Each region corresponds to a region of a given depth. The method for rendering a non-photorealistic content includes generation of a segmented image having at least one segmented region generated with a given segmentation scale. The at least one segmented region corresponds to at least one region of the set of regions. A binary edge image is generated in which at least one binary edge region is generated with a given edge extraction scale, the at least one binary edge region corresponding to at least one region of the set of regions. The non-photorealistic content is rendered by combining the segmented image and the binary edge image.

Abstract: An apparatus and a method for controlling the same by a user are suggested. The suggested apparatus comprises: a detecting unit for detecting a first event executed by a user in relation to a plurality of devices including the apparatus; a control unit for generating a second event according to the first event detected by the detecting unit; an output unit for presenting the second event to the user, wherein the control unit generates a command for executing the first event on the apparatus as a function of a response of the user to the second event detected by the detecting unit. The suggested apparatus and method are suitable to provide a second event, before executing a command corresponding to a first event from the user, for the user to confirm the intention of the first event.

Abstract: The present invention relates to the domain of control devices for virtual games, and more specifically to a control device to control the displacement of a virtual player and of a virtual ball in the scope of a football video game. According to the invention, the control device is in the form of a ball connected to a pedestal. This ball is equipped with accelerometers able to detect a displacement force on the ball as a result of a strike exerted on said ball, pressure sensors able to detect a pressure force exerted on the surface of the ball and a processing module. The processor module generates using information from the accelerometers and pressure sensors control signals to control the displacement of the virtual ball in the video game and control signals to control the displacement of the virtual player in the video game.

Abstract: The invention relates to a method for processing video images comprising the steps for acquiring a plurality of video images during a time interval comprising a reference time t; associating a weighting factor with each of the video images, at least two of the video images having different weighting factors; memorising the video images; weighting each of the video images memorised with the associated weighting factor; generating an image called the reference image associated with the reference time t by averaging weighted video images. According to the invention, each video image is memorised with a resolution proportional to the weighting factor associated with said video image in order to reduce the memory space necessary for the storage of images and reduce the access time to the memorised images.

Abstract: A method and an apparatus for generating the depth map of a scene are described. The method comprises the steps of: projecting a structured light pattern with homogeneous density onto the scene to obtain a first depth map; segmenting the scene into at least one area based on the depth information in the first depth map; and projecting a structured light pattern with a heterogeneous density onto the scene by adapting the density of the light pattern to the at least one area of the scene to obtain a second depth map of the scene.

Abstract: The present invention concerns a method at a file server for sending more than one file to more than one receiver, comprising the steps of aggregating the files into a container, splitting the container into more than one packet, and transmitting the more than one packet to the more than one receiver, wherein, the reception of at least one packet of the container enables a receiver to request the reception of lost packets of the container. To this end, the method comprises the steps of receiving an indication of the number of consecutive lost packets of the container per the more than one receiver and adapting the size of the container, in function of the number of consecutive lost packets at the receivers.
