5. Purpose of the System • Image Enhancement • Color & Density • Select Portions of the Image and Identify • Predetermined List of Object Types • Automatically Detect an 18% Gray Card

6. Gray Card • A card that reflects a known percentage of the light falling on it.  • Has a neutral gray finish that has an 18 percent reflectance. • Used to provide a known gray tone in color work.

7. Gray Card Correction Original Image Corrected Image • This example shows the Global Enhancement correction applied to the main image.

8. Objectives and Success Criteria • Document, Design, Implement, and Produce • Software can Run on any PC that meets the Hardware Requirements • Simplify the Task of Color and Density Correction • Enhance the Overall Quality of Digital Image

9. Functional Requirements • Graphical User Interface • Open, Read, Display, and Save TIFF images • Preview Feature • One Level Undo Feature • Correction • Automatic and Manual Corrections • Single selection or multiple selections • Full Amount or Percentage of Suggested Correction • Entire Image or Selected Portion(s)

10. Functional (cont.) • Selection Tool • Pixel Group, Ellipse, or Rectangle • Identify the Area • Predetermined List of Object Types • Suggested Correction • Stored RGB Values

11. Functional (cont.) • Image Display • Default—1 to 1 • Display Options • Zoom Capability • Scroll Bars

12. Nonfunctional Requirements • User Interface and Human Factors • Simple, User-friendly Graphical Interface • Tool Selection Palette • Integrated Help System • Documentation • Well Documented • Hardware Consideration • IBM compatible • 1 Ghz Pentium IV, 256 MB Ram • 24-bit true color, 1280x1024 - graphics card

13. Nonfunctional (cont.) • Performance Characteristics • Perform Corrections in a Timely Manner • Error Handling and Extreme Conditions • Program Should NOT Crash • Appropriate Error Messages

14. Nonfunctional (cont.) • Quality Issues • High Quality Corrected Images • Minimal Distortion • Aesthetically Correct • Density and Color • System Modifications • Easy to Modify Without Major Changes to System Design • Possibility for Further Development

15. Use Case Model

16. Client PC File Control Assistance Interface Enhance View Architecture

17. Subsystems • File Control • Initialize system variables • Open, close, and save images • Undo the last action • Exit

18. Subsystems (cont.) • View • Display an image to the screen • Zoom functionality • Scrolling functionality

19. Subsystems (cont.) • Enhance • Manual and auto enhancement functionality • Find Gray Card • Selection tools • Pixel group • Ellipse • Rectangle • Draw, Identify, and Average selections • Global or local change • Correction factor

21. Subsystem Decomposition

22. Persistent Data Management • All persistent data is stored using a file system. • TIFF files are used to store the images files. • RGB values for the predetermined object types are stored in a text file containing markup tags.

23. Stored Objects File <n>Grass<v>131, 157, 59<e> <s2>Caucasion<s1>Skin<n>Average<v>200, 145, 120<e> <s2>Indian<s1>Skin<n>Average<v>175, 115, 65<e> <s2>African<s1>Skin<n>Light<v>191, 140, 110<e> <s2>African<s1>Skin<n>Medium<v>170, 135, 90<e> <s2>African<s1>Skin<n>Dark<v>115, 80, 70<e> <end>

24. Main Interface

25. Main Interface • Main interface with a TIFF image loaded.

26. Find Gray Card

27. Select Gray Card • Allows user to manually select gray card

28. Auto Enhance Preview • Dynamically displays preview of changes as the slider control is moved.

29. Manual Enhance Preview • Dynamically displays preview of changes as the slider control is moved.

30. Manual Enhance Preview • Dynamically displays local and global change as radio button is changed.

31. Process Plan • Evolutionary Delivery • Client • Early Prototype • Early Discovery • Difficulties with Specific Features • Delivery • Product with the Most Important Functionality • No room for extension of deadline

36. Implementation

37. Implementation (cont.) • Development Platform • Microsoft Visual C++ 6.0 • User Interface • Microsoft Foundation Class • Underlying system • C++ • CxImage Library • Open source libraries for image processing

38. Demonstration • FotoGazmic Software

39. Module Testing • Performed numerous test cases on each code module • Documented test cases and results • Lead tester in charge

40. Integration Testing • Individual Components • Assessed Dependencies of Modules

41. System Testing • Ensured Functional and Nonfunctional Requirements • Included Functional and Performance Testing

42. Acceptance Testing • Internal Acceptance Test • Team Members • Acceptance Test with Client

43. Deployment & Training • Installation Plan • We did not install the FotoGazmic software package on any of the clients’ computers. • Source code and a compiled executable are available on our project web site. • Full documentation of the software is provided. • Installation is accomplished using a standard setup package.

44. Deployment & Training (cont.) • For FotoGazmic users, we have created: • An integrated help system

45. Retrospective Thoughts • We needed better version control • Evolutionary delivery worked extremely well • Dividing the project among team members worked well • We learned a lot about software development & project planning • Creating a system from the ground up was quite difficult!
