Student Projects
Overall, we had an excellent collection of student project proposal:
- Identifying and writing extractors for finding metadata of use to social network analysis.
- Compare 2 different disk images and present the differences nicely.
- Improve error handling of aimage
- Analysis of Microsoft Access and Outlook databases.
- Analysis of existing face recognition algorithms.
- Research methods of permanent deletion of information from secondary storage.
- Reporting an individual's online history
- Analyze the Chip Drive Smart Card Reader and Chip Drive USB Sim Card Stick

Today's Tools Class
- Image File formats
- Online resources for working with images
- Tools available for working with images

Lab
In today's lab I would like to have students research various image processing toolkits available and report back before the end of the class. I will download in advance and make available two data sets:
- CS4920faces.zip - a collection of faces
- CS4920docs.zip - a collection of document files, publicly available.
