Abstract: For table structure recognition in document processing, a methodology can use 2-click human interaction to define bounding box of the table and convert OCR data into n-dim positioning for column-wise and row-wise assignment. An adaptive filter can identify and assign column-like morphologies in tables. An adaptive cycle based column/row assignment can select best methodology for each table. Column overlap and merge detection can use post-processing for complex table structures. Data storage and feedback mechanisms can be used for adaptive template predictions.
