Image Fusion: an Introduction to Multispectral Signal Processing

A new generation of affordable infrared (IR) cameras provides both IR and visible images, which allows professors to introduce the concept of multispectral (and hyperspectral) signal processing in a particularly motivating way for students. We describe the use of a FLIR E60 camera in a graduate digital image processing course, in which IR and visible images were used as the basis for an open-ended final project in the course. We used both pre- and post-project questionnaires to confirm that the project was a positive experience for the students, and helped motivate them to master the course material.
