摘要: The invention relates to a system (5, 15) and a method for detecting and annotating faces on-the-fly in video data. The annotation (29) is performed by modifying the pixel content of the video and is thereby independent of file types, protocols and standards. The invention can also perform real-time face-recognition by comparing detected faces with known faces from storage, so that the annotation can contain personal information (38) relating to the face. The invention can be applied at either end of a transmission channel and is particularly applicable in videoconferences, Internet classrooms, etc.

摘要: The present invention relates to a method for a system (101) of performing a dialogue communication with a user (105). The user's speech signal (107), which comprises a request of an action to be performed by the system (101), is recorded and analyzed. The result of the analyzing is compared with predefined semantic items (103) defined in the system (101), wherein an action is associated with each of the semantic items. Based on the comparison a candidate list (109), which identifies a limited number of semantic items (111, 113) selected from the predefined semantic items (103) is generated and presented to the user (105). An action associated with one the semantic item in the candidate list (109) is performed based on predefined criteria, unless the user (105) chooses a different semantic item from the candidate list (109).
