After the preliminary investigation, it is the time for us to go to the kernel -- the design stage. Since the further implementations are all based on this design report. the details should be involved clearly. go to next page introduction go to previous page

Being a successful secretary in the office, good typing skills is need. However, if a big pile of document is waiting for you, OCR is you good assistant.

go to next page detail of ‘word recognition’ modules go to previous page 7. pre and post conditions The important variant on the data structure is the script record and the word bank. If the script change, the object will be changed. If the word bank change, word can not be recognize correctly. 8. error handlingError may cause by the memory jam. It will happen when the script file contain too many words. If error occurs, user will be asked to break the script file into two subfiles. 9. test caseTest this software with different size of script files and open them altogether in order to test the software memory management.
