Abstract

A method, apparatus and article of manufacture for creating visualizations of electronic audiovisual compositions are described. In one embodiment, a method comprises: receiving an electronic composition description; rendering a visual representation of electronic visual composition description; generating a content description that includes semantic information and location information for elements within the electronic audiovisual composition description; identifying one or more audible, visual, and audiovisual elements from the content description; and generating a multimedia overview of the electronic composition description that includes a selected set of the identified one or more audible, visual, and audiovisual elements.

Claims

1. A method comprising

receiving an electronic composition description;

rendering a visual representation of electronic visual composition description;

generating a content description that includes semantic information and location information for elements within the electronic composition description;

identifying at least one of an audible, visual, an audiovisual element from the content description; and

generating a multimedia overview of the electronic composition description that includes a selected set of the identified audible, visual, and audiovisual elements.

2. The method defined in claim 1 wherein the electronic composition description is a description of a real-time rendered document.

3. The method defined in claim 1 wherein the electronic composition description is a description of a presentation document.

4. The method defined in claim 1 wherein the electronic composition description is a description of a non-document image.

5. The method defined in claim 4 further comprising:

processing the image including performing at least one of, rectifying a contrast of the picture image, or enhancing a color content of the image; and

generating the multimedia overview of the electronic composition description from the identified one or more audible, visual, and visual elements, and the processed picture image.

6. The method defined in claim 4 further comprising:

segmenting text regions of the non-document image;

selecting one or more text regions from among the segmented text regions;

determining an order of the selected one or more text regions; and

generating the multimedia overview of the electronic composition description from the identified audible, visual, and audiovisual elements, and the selected one or more text regions based on the determined order of those regions.

7. The method of claim 6, wherein the order is a time order determined from received timing data corresponding to the segmented text regions.

8. The method defined in claim 6 further comprising:

performing handwriting recognition on each of the segmented text regions to generate semantic content from the text regions; and

generating the multimedia overview of the electronic visual composition description from the identified one or more audible, visual, and audiovisual elements, and the semantic content obtained from the text regions.

9. The method defined in claim 1 wherein the electronic visual composition description is a description of a document that includes one or more time attributes associated with the electronic visual composition.

10. The method defined in claim 1, wherein the generating a multimedia overview of the electronic visual composition comprises:

selecting a set of one or more of the identified one or more audible, visual and audiovisual elements for inclusion into the multimedia overview is based on time and information content attributes.

11. The method defined in claim 10 wherein the information content attributes are based on one or more of application, user specific, and display size of a device for which the multimedia overview is being generated constraints.

12. The method defined in claim 1 wherein the generating the multimedia overview further comprises composing the multimedia overview using the set of one or more of the audible, visual and audiovisual elements comprises outputting a navigation path representation by which the set of one or more of the audible, visual and audiovisual elements are processed when creating the multimedia representation.

13. The method defined in claim 1 further comprises:

rendering a visual representation of the electronic composition;

extracting one or more audible, visual, and audiovisual elements from the rendered visual representation; and

content matching the extracted one or more audible, visual) and audiovisual elements and the identified one or more audible, visual, and audiovisual elements, to obtain a more accurate set of one or more audible, visual, and audiovisual elements; and

generating the multimedia overview with a set of one or more audible, visual, and audiovisual elements selected from the more accurate set of one or more audible, visual, and audiovisual elements.

14. The method defined in claim 1 further comprises:

extracting multimedia content from the received electronic composition description; and

rendering the extracted multimedia content in the multimedia overview.

15. The method of claim 1 further comprises:

extracting an order of the one or more audible, visual, and audiovisual elements from the content description.

16. An article of manufacture having one or more recordable media with instructions thereon which, when executed by a system, cause the system to perform a method comprising:

receiving an electronic visual composition description;

rendering a visual representation of electronic composition description;

generating a content description that includes semantic information and location information for elements within the electronic composition description;

identifying at least one audible, visual, or audiovisual element from the content description; and

generating a multimedia overview of the electronic composition description that includes a selected set of the identified audible, visual, and audiovisual elements.

17. A system comprising:

an analyzer to receive an electronic composition description, the analyzer to further,

render a visual representation of the electronic composition description,

generate a content description that includes semantic information and location information for elements within the electronic composition description, and

identify at least one audible, visual, and audiovisual element from the content description;

a selector to select portions of the identified audible, visual, and audiovisual elements for inclusion into a multimedia overview of the electronic composition description; and

a synthesizer to compose the multimedia overview with synchronized audible information based on the selected audible elements, visual information based on the selected visual elements, and audiovisual information based on the selected audiovisual elements.
