摘要:
The invention relates to a device and a method for processing information of a database. The device consists of means for pre-defining at least one related area in a representation space comprising positions that can receive elements that are representative of the data, said space including at least one complementary area having no data representation. It also comprises means for specifying at least one data bootstrapping element for each related area, positioning the bootstrapping elements at bootstrapping positions in the related areas, successively determining new elements from elements already positioned, in accordance with at least one proximity order relation based on contents of the data, and successively positioning the new elements at positions neighboring the positions occupied by the data elements already positioned.

The present invention relates to a system and a method of security for a firewall. The system comprises means of communication with an application provided to make connections via the firewall, means of identifying at least one delegation parameter supplied by this application, provided to recognize this application as capable of establishing connections when the delegation parameter complies with at least one reference parameter and command means for establishing connections, based on requests originating from this application. The security system also comprises means of producing the reference parameter, including means of automatic generation and/or command means for automatic distribution, to a list of permitted users, of the reference parameter. It is thus possible to communicate in advance to users the reference parameter to be supplied as the delegation parameter.

A method of filtering a disparity mesh from pixel images according to the invention, where the disparity mesh comprises a plurality of points, where each point is associated with values of two planar coordinates (X, Y) and a disparity value (D) and where the values are quantization pitches, comprises the step: filtering planes by filtering 2D-lines in 2D-spaces (X-D, Y-D) of the planar coordinates (X,Y) and the disparity (D).
摘要:
A method for coding a 3D video signal is described. The coding method comprises a step of coding current, depth and occlusion images. According to the invention, the current occlusion image is coded according to the following steps for: coding for each block of the current occlusion image a binary identifier indicating if said block is coded or not, and coding occlusion data for each block for which the binary identifier indicates that the block is coded.
摘要:
A method is disclosed that allows a content provider to transmit font information to a receiver, and that further allows a receiver terminal to receive and apply such information, thus giving improved possibilities for the content provider to define how to render the transmitted text or symbols on a display. The method is good for data streaming systems, in particular MPEG-4 based systems. Advantageously, the received font information can be stored if the terminal contains an appropriate storage device.
摘要:
The device for addressing a plasma panel comprising a video processing circuit (7) for processing the digital video data received, a correspondence memory (8) for transcoding these data, a video memory (9) for storing the transcoded data, the video memory being linked to column driver circuits (10) for controlling the column addressing of the plasma panel, is characterized in that the transcoded data have a greater number of bits than the digital video data received and in that the processing circuit (7) comprises means for differently coding identical values of digital video data received. The applications target plasma panel control devices.

摘要:
The invention concerns a device receiving data associated with a first profile and generating data associated with a second profile, comprising means to extract facts associated with the first profile, means to extract facts associated with the second profile, a set of rules describing a way to modify facts associated with said first profile into facts associated with said second profile, means to analyze said facts associated with the first profile and said facts associated with the second profile, means to modify facts associated with said first profile into facts associated with said second profile according to said set of rules. The device is characterized in that it comprises, means to request additional rules when said set of rules does not allow to modify facts associated with said first profile into facts associated with said second profile.
摘要:
The method comprises the following steps: partitioning of the 2D image into 2D zones as a function of the depths assigned to the pixels, a zone being defined by a minimum and maximum depth, calculation of blur of a 2D zone by convolution for the pixels on either side of the boundary with another zone, the size of the convolution kernel being dependent on the depth of the pixels of the 2D zone processed. Applications are the creation of special effects for video games, film production.
