摘要:
Multimedia content containing moving pictures and audio is divided into multiple scenes and metadata is generated for each of the scenes obtained as a result of the division. It is possible to generate metadata containing scene structure information metadata that describes the hierarchical structure of the content in addition to scene section information and titles. Also, a name or an identifier of each descriptor contained in the metadata is described as hint information for manipulation of metadata composed of at least one descriptor describing semantic content, a structure, and characteristics of content.
摘要:
A metadata extraction unit has a feature point selection and motion estimation unit 62 for extracting at least one feature point representing characteristics of the video/audio signals in a compressed domain of the video/audio signals. Thus, reduction of time or cost for processing can be realized and it makes it possible to process effectively.

The present invention relates to a technique for displaying a characteristic image or scene of video data as a thumbnail so that a user can easily understand the contents of the video data. Video data is inputted, the data describing an important scene in the video data is inputted or generated, and a thumbnail of the important scene indicated in the important scene data is generated. The inputted video data is reproduced, the reproduced video and the thumbnail are displayed, and the important scene in the video data is displayed in a thumbnail. Alternatively, an image at an arbitrary position of the important scene or at the beginning or at a position where an audio data power is at its peak is made a thumbnail image and a thumbnail image is generated from the important scene in the video data for display.

This invention provides a moving picture data processing method for extracting a portion of moving picture data from moving picture data. The method comprises: a frame picture evaluation step of evaluating each of a plurality of frame picture data included in the moving picture data on a basis of a specific condition, for generating first picture evaluation values depending on the evaluations; and a moving picture data extraction step of extracting moving picture data including a plurality of frame picture data that meet a specific condition, in response to the first picture evaluation values.
摘要:
A method and apparatus for storing video data is provided. Video data, that comprises a series of frames, is received. Information about changes that are detected in the series of frames is generated. The information is aggregated to generate a plurality of video data change records. Each video data change record corresponds to a plurality of frames and includes change information that indicates changes that were detected relative to the corresponding plurality of frames. Events of interest that satisfy specified search criteria are searched for by comparing the specified search criteria against change information in one or more of the plurality of video data change records.
摘要:
In a computer program, a video input file and data input is segmented into individual play records so that each individual play can be displayed and manipulated by a user interface. If the video input file is digital, time stamps within the input file are used to segment the input file into individual play video files. Speech input is used to control the computer program and enter statistical information.

An apparatus for retrieving moving image according to the present invention has an extracting unit for extracting the information of the feature quantity of the moving image from the fixed moving image data, an extracting unit for extracting the information of the unique identification of the moving image to identify the moving image according to the information of the feature quantity of the moving image, and a retrieving unit for retrieving and identifying the fixed moving image from the object moving image for retrieving by comparing the information of the unique identification of the moving image with the information of the unique identification of the moving image beforehand extracted from the object moving image. Therefore, the information of the unique identification of the moving image for retrieving the moving image depends on the content of the moving image can be extracted, consequently, the identical moving image can be retrieved and identified from the moving image by using the information of the unique identification of the moving image at high speed.

The present invention relates to a method of determining a sequence of intensity measures corresponding to each of a sequence of video frames, the method being used particularly but not exclusively for selection of videos according to user preferences and for providing highlights from a video sequence. The method uses low level video characteristics which may be related to the to arousal and valence affects conveyed to a viewer whilst watching the video recording.
