In this lesson, learners use a Web-based customized version of ImageJ to investigate the properties of digital images as they relate to forensic science. Several images are taken from criminal evidence (ATM documents, license plates, etc.), but require image enhancement to reveal full detail. A set of micrographs of hair samples is also provided, and, after classifying and measuring the samples, students are able to identify the suspect most likely to have been at the crime scene.
This set of course materials includes lecture slides, activity files, images, quizzes, tests, review questions, and project assignments for Digital Media at Georgia Gwinnett College. The course uses open-source applications such as GIMP and InkScape.
Individual chapters are available for download due to the large file sizes. Web-based assignments to supplement these materials are located on the GGC Wiki: All Digital Media Assignments

This activity card is meant to be a self-paced lesson showing users how to process digital images.
This activity was originally developed by Intel® as part of the Intel® Learn Easy Steps program.
Here learners use WebImage, a Web-based customized version of ImageJ, (a) to investigate the nature of fading in old photographs and (b) to correct it digitally. Several digital images of faded photographs are provided, and, with a simple technique, students can enhance the brightness and contrast of the images. This lesson introduces students to simple image arithmetic with opportunities to perform and evaluate each operation.
Understanding Evolution provides a large collection of images and illustrations you may download and use in lectures and presentations to help explain the concepts of evolution.
