Definition of “Real-Time” Concept

“Real-time” is an elusive term that is often used to describe a wide variety of image/video processing systems and algorithms. Considering the need for real-time image/video processing and how this need can be met by exploiting the inherent parallelism in an algorithm, it becomes important to discuss what exactly is meant by the term “real-time”. From the literature, it can be derived that there are three main interpretations of the concept of “real-time,” namely real-time in the perceptual sense, real-time in the software engineering sense, and real-time in the signal processing sense.
