Abstract
An electronic document comparison system and method removes cachets and noise from a test electronic document. The system and method further compares each of second minimum blocks with a corresponding first minimum block in a standard electronic document line by line, and obtains the second minimum blocks having different coordinates on each line. Furthermore, the system and method simplifies the obtained second minimum blocks having different coordinates by filtering designated objects, and marks the simplified second minimum blocks in the test electronic document.
Claims19
An electronic document comparison system, comprising:
- a storage system;
- a database system that stores a standard electronic document;
- at least one processor;
- and
- an electronic document comparison unit stored in the storage system and being executable by the at least one processor, the electronic document comparison unit comprising:
- a preprocessing module operable to preprocess a test electronic document to remove cachets and noise from the test electronic document;
- an identifying module operable to identify the test electronic document using optical character recognition (OCR), and generate a plurality of second minimum blocks and obtain coordinates of each of the second minimum blocks;
- a comparison module operable to compare each of the second minimum blocks with a corresponding first minimum block in the standard electronic document line by line, and obtain the second minimum blocks having different coordinates on each line;
- a filtration module operable to simplify the obtained second minimum blocks having different coordinates by filtering designated objects;
- and
- a mark module operable to mark the simplified second minimum blocks in the test electronic document.
