摘要： A texture-based text localization system proceeds directly in the compressed domain for DCT compressed JPEG images or MPEG videos. The DCT coefficient values in JPEG images and MPEG videos, which capture the directionality and periodicity of local image blocks, are used as texture feature measures to classify text areas. Each unit block in the compressed images is classified as either text or nontext. In addition, post-processing in both the compressed domain and the reconstructed candidate text areas can be used to refine the results. For video frames that contain text, the displacement of text between two consecutive frames is estimated which gives the velocity of the moving text. This temporal displacement information is also used to further refine the localization results. The text is then processed to provide content or speech output.

摘要： A large web page is analyzed and partitioned into smaller sub-pages so that a user can navigate the web page on a small form factor device. The user can browse the sub-pages to find and read information in the content of the large web page. The partitioning can be performed at a web server, an edge server, at the small form factor device, or can be distributed across one or more such devices. The analysis leverages design habits of a web page author to extract a representation structure of an authored web page. The extracted representation structure includes high level structure using several markup language tag selection rules and low level structure using visual boundary detection in which visual units of the low level structure are provided by clustering markup language tags. User viewing habits can be learned to display favorite parts of a web page.

摘要： An image processing system for automatically extracting image frames suitable for printing and/or visual presentation from a compressed image data is described. The image processing system includes a face detector that detects if an image frame contains at least a face. The image processing system also includes a blur detector that determines the blur indicator value of the image frame directly using the information contained in the compressed image data if the image frame is determined to contain a face. The blur detector indicates that the image frame is suitable for printing and/or visual presentation if the blur indicator value of the image frame is less than a predetermined threshold. The image processing system may also include a motion analyzer that determines if the image frame is a super-resolution image frame suitable for printing and/or visual presentation if the image frame does not contain any face. The image processing system may also include a face tracker that detects if the image frame contains a non-frontal face.
