GScan

Introduction

 

GScan is a data capturing system for massive documents. In lot of the cases, we need to digitalize the physical documents in to images and indexed data for record keeping, easy retrieval and analyze, and extract knowledge from physical documents, questionnaires or application forms. As quantity of the forms is huge, we need pipe-lining processing: scanning, indexing, quality control and data export are worked in parallel, it implies that role-based access control, workflow, scalability of the system are important and well handled in this system.

 

 

System architecture

 

GScan is designed in server-client model and template architecture, targeted for massive standard form processing. User may define the fields such as OCR*, ICR*, OMR, 1D Barcodes, Image clipping, Manual input types for data capturing as templates.
