Introducing PAGE-XML: Streamlining Document Image Processing and Layout Analysis
In the world of document analysis and recognition, the ability to efficiently exchange, evaluate, and process document image data is of utmost importance. This is where PAGE-XML comes into play. PAGE-XML is a powerful XML format that serves as a standardized schema for representing page content, layout analysis, and document image dewarping.
PAGE-XML encompasses various XML formats, each defining a specific aspect of document analysis. The most actively used formats include:
-
PAGE XML for page content: This format captures the structure of a document page, including regions, text lines, words, glyphs, reading order, and text content. With PAGE XML, developers and researchers can efficiently represent and exchange complex page layouts, enabling seamless data interoperability in document analysis workflows.
-
PAGE XML for layout analysis evaluation: This format provides the means to evaluate layout analysis algorithms and systems. It allows researchers to define evaluation profiles, store evaluation results, and assess the performance of layout analysis methods accurately. By using PAGE XML for evaluation, researchers can benchmark and compare their algorithms against established standards.
-
PAGE XML for document image dewarping: This format focuses on dewarping grids, which are essential for correcting distortions introduced during the scanning process. By defining the dewarping grids using PAGE XML, researchers and developers can automate the dewarping process and ensure accurate representation of document content.
All the PAGE-XML formats are defined by XML schemas, which can be accessed officially on primaresearch.org. The schema URLs for the different formats are as follows:
-
PAGE XML for page content: pagecontent.xsd
-
PAGE XML for layout analysis evaluation: layouteval.xsd
-
PAGE XML for document image dewarping: dewarping.xsd
With PAGE-XML, document analysis professionals and researchers can benefit from a standardized and interoperable framework for tackling complex tasks, such as document image processing and layout analysis. By adhering to the PAGE-XML standard, developers can ensure compatibility, consistency, and seamless integration of their solutions.
To facilitate further exploration of PAGE-XML and its applications, the repository includes a comprehensive wiki with additional information. Whether you are an industry professional, researcher, or enthusiast in the field, PAGE-XML offers a powerful toolset to enhance your document analysis and recognition endeavors.
