Built template-based system for extracting table structures from invoices, including multi-line headers.
Line item extraction is difficult in invoice processing. Tables can have complex structures with multi-line headers. Need to match similar layouts reliably. Required accurate extraction for template-based approach.
Developed UI for users to draw tables on example invoices. Created layout matching algorithm. Supported complex table structures including multi-line headers. Enabled template reuse across similar invoice layouts.
Layout matching algorithm has not failed in production. Used in other company projects. Handles complex invoice table structures. Accurate extraction for matched layouts.
