| Summary: | 碩士 === 國立交通大學 === 資訊工程學系 === 85 === This thesis proposes an analysis and design of a medical
documents processing system,which includes techniques of
document analysis, character recognition and database construc-
tion. To integrate different modules designed by different
teams, we adopt an object-rientedsystem. This structure has
good reusability, efficiency, maintainability and flexibility.
Three steps are included in the object-oriented system. The
first step is static modeling, whichdescribes objects,
relationships among objects and the system hierarchy. Here,
objects aredefined by their attributes and funtions. The second
step is dynamic modeling, which descrbessystem events and states
flow control. The third step is functional modeling, which
describesdata flow in the system. In the document processing
system, we aim to process all kinds of medical documents.
Amedical document may contain graphics, image, text, stamps and
marks. The system will firstpreprocess the document and find out
blocks of all object components in the document. Graphics
blocks in the document will be vectorized; image blocks will be
compreseed; text blocks will be recognized by OCR modules; mark
blocks will be checked. All of these information iteamswill
finally be stored into a database, which can provide users
required information.
