Practical Assignment

In software engineering, Unified Modeling Language (UML) diagrams are a meaningful medium to draft and document system design. For already delivered systems such diagrams can be found in architecture descriptions, mostly embedded in other documents as bitmaps. Such embedding in bitmap files (JPG, PNG, BMP) makes them difficult to access for research, analysis and reuse by third parties. Your task is to develop an application capable of recognizing UML class diagrams in bitmap images and extracting them into XMI files. For the detailed information about XMI format, refer to the OMG XMI specification [PDF].

Templates

The following documentation artifacts have to be delivered in course of the project:

  • Software Development Plan [Word document]. The Software Development Plan is a comprehensive, composite artifact that gathers all information required to manage the project. It encloses a number of artifacts developed during the inception phase and is maintained throughout the project.
  • Software Requirements Specification [Word document]. The requirements specification document provides an outline of the envisioned core requirements and the contractual basis for the more detailed technical requirements.
  • Configuration Management Plan [Word document]. The Configuration Management (CM) Plan describes all Configuration and Change Control Management (CCM) activities you will perform during the course of the product or project lifecycle. It details the schedule of activities, the assigned responsibilities, and the required resources, including staff, tools, and computer facilities.
  • Software Architecture Document [Word document]. The Software Architecture Document provides a comprehensive architectural overview of the system from different architectural viewpoints.
  • Design models (NO TEMPLATE). The design model is an object model describing the realization of use cases, and serves as an abstraction of the implementation model and its source code. The design model is used as essential input to activities in implementation and test. Use a UML design tool and deliver your design sufficiently documented in a PDF file. The document to be delivered should at least include a class diagram, a sequence diagram, an activity diagram and a state chart diagram.

Using Google Source Code Repository

The progress of each group will be tracked through an online repository just like in a normal software company. To use the repository you need to have a Google account. Send us your Gmail address and we will grant you access to the Image-to-UML project SVN repository at the Google Source Code. After that follow the instructions available at the Source tab of the SVN repository to access the project using your SVN client.

Image-to-UML repository address: http://code.google.com/p/image-to-uml/

Each group's directory should have the following structure and contain the following documents:

GroupX

  • Requirements: a) groupX_ieee_requirements.pdf, b) groupX_requirements_questionnaire.pdf
  • Analysis & Design: a) groupX_rup_sad.pdf, b) groupX_rup_cmpln.pdf, c) groupX_uml_design.pdf
  • Implementation: a) trunk (put your source code here), b) tags. Read more about the conventional use of the SVN trunk, branches and tags directories here [link].
  • Project Management: a) groupX_rup_sdpln.pdf

Available libraries for image processing and OCR (Optical Character Recognition)

(Note that this list is not complete. You are allowed to use any programming language and any library you find useful).

  • VC++: OpenCV, tesseract OCR, Asprise OCR (free trial)
  • Java: Algoritharium package, tesseract OCR, java OCR, Asprise OCR (free trial)
  • C#: AForge.NET Framework, MODI (Microsoft Office Document Imaging Library), tesseract OCR, Asprise OCR (free trial)

Test images

Samples of class diagram image files that your program should be able to parse can be found here [ZIP archive].
