Identify the primary elements and processes that form the system. It defines a goal-oriented set of interactions between external actors and the system. The primary elements are termed as “actors” and the processes are called use cases or actions. Actors are entities that will utilize the application in order to complete a task. An actor maybe a class of users, roles users can play or other systems. Cockburn (1997) distinguishes between primary and secondary actors. A primary actor is one having a goal requiring the assistance of the system. A secondary actor is one from which the system needs assistance. Since this project focuses more on the image processing phase, this particular use case diagram will focus on the secondary actor i.e. the web camera and its part in the functionality of the software.
