摘要： Caption boxes which are embedded in video content can be located and the text within the caption boxes decoded. Real time processing is enhanced by locating caption box regions in the compressed video domain (210) and performing pixel based processing operations within the region of the video frame in which a caption box is located. The captions boxes are further refined by identifying word regions (240) within the caption boxes and then applying character and word recognition processing (250) to the identified word regions. Domain based models are used to improve text recognition results. The extracted caption box text can be used to detect events of interest in the video content and a semantic model applied to extract a segment of video of the event of interest.

摘要： Systems and methods for describing video content establish video description records which include an object set (24), an object hierarchy (26) and entity relation graphs (28). Video objects can include global objects, segment objects and local objects. The video objects are further defined by a number of features organized in classes, which in turn are further defined by a number of feature descriptors (36, 38, and 40). The relationships (44) between and among the objects in the object set (24) are defined by the object hierarchy (26) and entity relation graphs (28). The video description records provide a standard vehicle for describing the content and context of video information for subsequent access and processing by computer applications such as search engines, filters and archive systems.

摘要： Digital watermarks can serve to indicate copyright ownership of digitized video. When video images are transmitted as transformed by discrete cosine transformation (DCT) for compression, with or without motion compensation, it is advantageous to include a watermark after transformation. To this end, a DCT watermark is generated for optimal visibility based on the original image data, and the generated watermark is superposed on the transformed data.

摘要： Methods and a system are disclosed for processing an echocardiogram video of a patient's heart. The echocardiogram comprises at least a first sequence of consecutive video frames corresponding to a first view of the patient's heart concatenated with a second sequence of consecutive video frames corresponding to a second view of the patient's heart. The end-diastole phase of the patient's heart is monitored in each frame by detecting the electrocardiograph wave, and a key frame is selected upon the occurrence of the R-wave peak in the electrocardiograph wave in each of the first sequence of consecutive video frames and in the second sequence of consecutive video frames. The shape and color content of the echocardiogram image window is monitored in certain video frames, and a transition is detected when there is a change in the first feature between adjacent frames. A summary is generated which comprises by the video frames corresponding to the end-diastole phase.

摘要： The invention provides a system and method for integrating multimedia descriptions in a way that allows humans, software components or devices to easily identify, represent, manage, retrieve, and categorize the multimedia content. In this manner, a user who may be interested in locating a specific piece of multimedia content from a database, Internet, or broadcast media, for example, may search for and find the multimedia content. In this regard, the invention provides a system and method that receives multimedia content and separates the multimedia content into separate components which are assigned to multimedia categories, such as image, video, audio, synthetic and text. Within each of the multimedia categories, the multimedia content is classified and descriptions of the multimedia content are generated. The descriptions are then formatted, integrated, using a multimedia integration description scheme, and the multimedia integration description is generated for the multimedia content. The multimedia description is then stored into a database. As a result, a user may query a search engine which then retrieves the multimedia content from the database whose integration description matches the query criteria specified by the user. The search engine can then provide the user a useful search result based on the multimedia integration description.
