Intelligent missive document processing system

An intelligent missive document processing system comprises: one system control unit as bridge of unit integration and data transfer in system, features four functions: filtering noise in document image sent from data input unit and converting it to connected component; sending connected component data of pre-processing unit to table processing unit; sending text image generated by table processing unit to text recognition unit; sending table file generated by table processing unit and text file generated by text recognition unit to output unit to display or save; one data input unit for converting document into digital image to feed pre-processing unit; one pre-processing unit for removing noise in document image sent from data input unit, and converting document image into connected component; one table processing unit for extract table features with connected component sent from pre-processing unit as basis, and one by one matching all features of table feature database stored in computer to confirm if the
