SYSTEM AND METHOD FOR EXTRACTING FLOWCHART INFORMATION FROM DIGITAL IMAGES

摘要

A system and method for extracting flowchart information from digital images is provided. The method includes converting the digital flowchart image into a grayscale image and then binarizing the image. The method further includes extracting and masking text data from the binarized image. Further, flow lines connecting geometric components within the flowchart image are extracted and masked. The geometric components are classified into one or more categories and the flow line relationships between the geometric components are extracted. Finally, the extracted text data, flow line relationship information and geometric component information is stored in a database.
