Students make measurements, collect and analyze data, and develop solutions as they work through each lesson. In a sample lesson, Digital Detective, students are presented with evidence images that have low contrast. They explore ways of revealing a clearer picture. Students also use a transparent overlay technique to compare a probable forged signature to signatures from the suspect. They qualify their observations by measuring the angle of slant and the ratio of sizes of uppercase to lowercase letters in signatures.
Students also enhance digital fingerprints and images of hair and tire treads as they solve crimes.
The teacher guide also includes student data sheets and summaries of the most frequently used image processing techniques organized in a series of quick reference pages suitable to copying. ENC does NOT distribute this resource. Advanced Technological Education Program.
