The first step in document processing technology is document analysis. "Document analysis technology" is used to analyze the layout of a scanned document to extract objects such as texts, diagrams, photographs and graphics, and separate them into their respective areas to generate basic data of each attributes, positions and sizes. These basic data are then processed with character recognition, vector conversion,*11 image processing, and compression by which high-quality documents are created.
- *11 Vector conversion
This refers to conversion into a graphic expression format (vector data) that saves shape information independent of resolution. This enables smooth contours to be maintained even when an image is enlarged.
