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 course provides an introduction to important philosophical questions about the mind, specifically those that are intimately connected with contemporary psychology and neuroscience. Are our concepts innate, or are they acquired by experience? (And what does it even mean to call a concept 'innate'?) Are 'mental images' pictures in the head? Is color in the mind or in the world? Is the mind nothing more than the brain? Can there be a science of consciousness? The course includes guest lectures by Philosophers and Cognitive Scientists."
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.
