The computer vision teaching modules were developed for use in several courses at the University of Nevada as part of a Combined Research and Curriculum Development (CRCD) project, sponsored by NSF. It was found that these modules can be used effectively at the community college level and can provide resources to community college faculty that they might not otherwise have readily available. A simple image viewer program can be used to display the before and after images and students can actually see and understand the effects of the transformation. Instructors wishing to include computer vision into their courses can easily modify a given module's contents and adopt all or parts of any given module.
Cloud Computing (CC) is widely adopted in sectors like education, healthcare, and banking due to its scalability and cost-effectiveness. However, its internet-based nature exposes it to cyber threats, necessitating ad...
