Better Use of Digital Images in Teaching and Learning

Abstract

Digital images are convenient and important media for describing and storing spatial, temporal, spectral, and physical components of information contained in a variety of domains. With the progress of electronics, sensors, computer equipment, and network infrastructure, today’s technology enables us to generate, acquire, manipulate, transmit, and store vast (online) image collections. The applications of images, which are expanding over wider and wider areas, have attracted more and more attention in recent years. The use of digital images in teaching and learning is one of the popular application areas.
