The invention relates to a method for changing a plane video to a stereoscopic video, based on real time human-computer conversation, which belongs to the multimedia technical field of computers. The method comprises that: a computer divides a whole video sequence into sub-sequences that have related contents; a user designates any frame of each sub-sequence as a key frame; the computer carries out wave-filtration to all plane video frames to enhance image edge information and sharpen the edge of the foreground objects of the video frame; foreground object segmentation is carried out to the key frames and non-key frames and profile curves and depth maps are extracted until depth map sequences corresponding to all the frames of the original plane video sequence are generated; the smoothed depth map sequences are utilized for rendering and generating multi-visual angle views corresponding to each moment, and the views are synthesized into stereoscopic video frames; the stereoscopic video frames of all the moments are composed into the stereoscopic video sequences. As the method is based on the real time human-computer conversation, the precise depth map of each frame can be obtained, thus well realizing the changing from the plane video to the stereoscopic video and finally obtaining the stereoscopic video with better effect.

Knowledge retrieving method of artificial intelligence dialogue and knowledge base automatic improving method

The invention provides a knowledge retrieving method of an artificial intelligence dialogue and a knowledge base automatic improving method. The knowledge retrieving method of the artificial intelligence dialogue comprises the steps of 1, obtaining a question statement of a user; 2, conducting semantic and intention analysis on the question statement to obtain a question identification; 3, according to the question identification, searching for a local answer in a local knowledge base; 4, obtaining the local answer, and fusing local question data and replying the local question data to the user; 5, when the local answer is not searched in the local knowledge base, according to the question identification, searching for a remote answer in a data source; 6, obtaining the remote answer, and fusing the remote answer and replying the remote answer to the user. According to the knowledge retrieving method of the artificial intelligence dialogue and the knowledge base automatic improving method, when the local knowledge base has no resource, the remote answer in the data source is searched for, and the occurrence that because entity coverage of a mapping knowledge domain is not sufficient, during a human-computer dialogue, a robot cannot give an answer is avoided.

Method for managing mixed initiative human-machine dialogues based on interactive speech

Method for managing mixed-initiative human-machine dialogues based on speech interaction exploiting the separation between a general dialogue knowledge, such as communicative acts, which can be used in multiple application domains, and particular linguistic knowledge, which are domain-specific parameters, to process the dialogue as a sequence of changes of status. Each status consist in a set of features linked both to the processed parameters and to the linguistic and pragmatic context, and describes a certain instant of the communicative situation between the user and the system so to discriminate it from other situations that are also only slightly different. The method employs three components. A first component which, given the various parameters of the domain, defines the parameters on which to intervene to modify the status with the intent of converging towards a situation in which all parameters are acquired with a certain value; in parallel, the component identifies the Communicative Act (CA) which applied to these parameters can make the status evolve in the required direction. A second component creates the sentences to be conveyed to user, whereby obtaining a Communicative Act by instancing said parameters. A third component analyses the user's reply to determine the new system status given the parameters that were provided by the user, their mutual coherence, the previous status of these parameters and other correlated parameters.
