To demonstrate higher-level image processing and analysis to third-year students enrolled in OPTM3201, I created a program to show students how to use R and the Image Magick library to perform basic image processing and analysis routines in ways that are based on our understanding of how human visual cells work. Students learn about the concepts of spatial filtering, image enhancement and simple feature detection in the process as applied to ocular imaging of corneal nerves seen when using ‘in vivo’ confocal microscopy. The direct industry relevance to clinical sciences is made immediately apparent through applied examples provided in class.
