摘要： An algorithm for finding regions of interest (ROI) in images and photos based on an information driven approach in which sub-blocks of an image are analyzed for information content or compressibility based on the discrete cosine transform. The sub-blocks of low compressibility are grouped into ROIs using a morphological technique. Unlike other algorithms that are geared for highly specific types of ROI (e.g. face detection), the method of the present invention is generally applicable to arbitrary images and photos. A center-weighted variation of the algorithm can produce better results for certain photo applications. The algorithm can be used with several other image applications, including Stained-Glass collages and Pan-and-Scan presentations.

摘要： In one embodiment, the present invention extracts video regions of interest from one or more videos and generates a highly condensed visual summary of the videos. The video regions of interest are extracted based on to energy, movement, face or other object detection methods, associated data or external input, or some other feature of the video. In another embodiment, the present invention extracts regions of interest from images and generates highly condensed visual summaries of the images. The highly condensed visual summary is generated by laying out germs on a canvas and then filling the spaces between the germs. The result is a visual summary that resembles a stained glass window having cells of varying shape. The germs may be laid out by temporal order, color histogram, similarity, according to a desired pattern, size, or some other manner. The people, objects and other visual content in the germs appear larger and become easier to see. The visual summary of the present invention utilizes important regions within the key frames, leading to more condensed summaries that are well suitable for small screens.

摘要： A computer-based method is provided for enabling navigation of video using a keyframe-based video browser on a display device with a limited screen size, for a video segmented into video shots. The video shots are clustered by similarity, while temporal order of the video shots is maintained. A hierarchically organized navigation tree is produced for the clusters of video shots, while the path lengths of the tree are minimized.

摘要： A hypervideo summary comprised of multiple levels of related content and appropriate navigational links can be automatically generated from a media file such as a linear video. A number of algorithms and selection criteria can be used to modify how such a summary is generated. Viewers of an automatically-generated hypervideo summary can interactively select the amount of detail displayed for each portion of the summary. This selection can be done by following explicit navigational links, or by changing between media channels that are mapped to the various levels of related content.This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

摘要： A method for creating multimedia meeting minutes is disclosed. In an embodiment, the method receives notations from a user. As each notation is received, context information is recorded with the notation. The context information is used to select pertinent portions of multimedia information received concurrently with the notations. An association is then created between the notation and each selected portion of the multimedia information. These associations may be used to access the selected portions of the multimedia information from the notations. The notations and their respective associations are deposited for future retrieval. The deposited notations may be revised by receiving an altered copy of the notations from a user. The deposited notations are modified in accordance with the altered copy.

摘要： Methods for interactive selecting video queries consisting of training images from a video for a video similarity search and for displaying the results of the similarity search are disclosed. The user selects a time interval in the video as a query definition of training images for training an image class statistical model. Time intervals can be as short as one frame or consist of disjoint segments or shots. A statistical model of the image class defined by the training images is calculated on-the-fly from feature vectors extracted from transforms of the training images. For each frame in the video, a feature vector is extracted from the transform of the frame, and a similarity measure is calculated using the feature vector and the image class statistical model. The similarity measure is derived from the likelihood of a Gaussian model producing the frame. The similarity is then presented graphically, which allows the time structure of the video to be visualized and browsed. Similarity can be rapidly calculated for other video files as well, which enables content-based retrieval by example. A content-aware video browser featuring interactive similarity measurement is presented. A method for selecting training segments involves mouse click-and-drag operations over a time bar representing the duration of the video; similarity results are displayed as shades in the time bar. Another method involves selecting periodic frames of the video as endpoints for the training segment.

摘要： The invention displays video search results in a form that makes it easy for users to determine which results are truly relevant. Each story returned as a search result is visualized as a collage of keyframes from the story's shots. The selected keyframes and their sizes depend on the corresponding shots' respective relevance. Shot relevance depends on the search retrieval score of the shot and, in some embodiments, also depends on the search retrieval score of the shot's parent story. Once areas have been determined, the keyframes are scaled and/or cropped to fit into the area. In one embodiment, users can mark one or more shots as being relevant to the search. In one embodiment, a timeline is created and displayed with one or more neighbor stories that are each part of the video and which are closest in time of creation to the selected story.
