380 results about "Information synthesis" patented technology

Information synthesis is the process of analyzing and evaluating information from various sources, making connections between the information found, and combining the recently acquired information with prior knowledge to create something new. Information synthesis strategies are essential skills.

Translation server, translation method and program therefor

A translation server connected to a terminal via a network, comprises: an input information controller for receiving a translation instruction sent from the terminal, the translation instruction including location information representing a location of an object document to be translated, source language information representing an source language of the object document and target language information representing a translation target language of the object document, and obtaining the object document to be translated from a Web server on the basis of the location information; an information separator for separating the object document sent from the input information controller into a translation object part and a non-translation object part; a translator for translating the translation object part sent from the information separator according to the source language information and the target language information to obtain a translation result; an information converter for producing a retranslation instruction part for permitting the terminal to display a language information input column for inputting the source language information and the target language information by the user and a retranslation instruction input part and to send the translation instruction including the source language information and the target language information in the language information input column and the location information of the object document to be translated to the translation server; and an information synthesizer for synthesizing the translation result sent from the translator, the retranslation instruction part produced by the information converter and the non-translation object part sent from the information separator and sending a synthesized result to the terminal. As a result, the terminal sends a new translation instruction including the changed language information of the object document to the translation server and operability is effectively improved.

Method and system for reducing codebook search-based precoding feedback bits of MIMO-OFDM system

Provided is a MIMO-OFDM system codebook search based reducing procode feedback information bit number method and device which is used in the air interface communication between users and the base station. The users include the channel state information acquisition unit and a channel variation tracing unit. According to the channel state information, the corresponding largest singular values of MIMO channel matrix are extracted from each OFDM sub channel and according to the sequence of OFDM sub channel, the largest singular values can be viewed as points on a smooth curve and the pole can be found. The codebook search unit searches the complete codebook to the sub channel corresponding to the pole and obtains the corresponding complete codebook procode vector serial number. The sub channeles which ar not corresponded to the pole are divided into a number of groups according to the sequence of OFDM channel, and the construction and searching methods of sub codebook are used to obtain the procode codebook vector sub codebook serial number for each group of sub channels which are not corresponded to the pole. The feedback information integration unit feedbacks the series of codebook vector serial number information to the transmitting end.

Hand posture estimation system and method based on RGBD fusion network

The invention provides a hand posture estimation system and method based on an RGBD fusion network. The system comprises a global depth feature extraction module, a residual module, a multi-mode feature fusion module and a branch parallel interference elimination module. The global depth feature extraction module adopts two parallel paths of cross-fused residual networks, wherein the upper path isa high-resolution feature map, the lower path is a low-resolution feature map, carries out the multi-scale feature fusion by the cross-fusing multi-resolution information, and finally predicts the network output in a high-resolution feature map. An input part of the system is divided into a depth image processing branch and an RGB color image processing branch, the features extracted by the two branches are subjected to multi-mode fusion to form the global features, the global features are sent to a branch parallel interference elimination module to perform feature extraction of hand branches, and the reinforced hand branch features are obtained and used for final joint position prediction. According to the method, the hand posture estimation with higher accuracy is achieved mainly through the information synthesis of the color images and the depth images.
