Abstract:
A method for analyzing a structure of a document image to make a table of contents having a title, an author and an abstract, comprising the steps of:dividing the document image into a number of regions and classifying the divided regions into text regions and non-text regions according to attributes of the regions; selecting candidate regions representing an abstract region and an introduction region, extracting word regions from the candidate regions, and determining an abstract content portion, said candidate regions being selected from the divided regions when a horizontal length of each of the divided regions is smaller than eight times an average horizontal length of the text regions, and said word regions being extracted from the candidate regions based on a determination probability; separating the title and the author using a basic structure form and a type definition representing an arrangement of journals; and recognizing a content of the title, author and abstract region to generate said table of contents.
