Face Recognition Attendance System Class Diagram

Face Recognition Attendance System Class Diagram (UML)

The face recognition attendance system class diagram is an illustration of the Unified Modeling Language’s (UML) class relationships and source code dependencies. Its class describes the methods and variables of an object, which is a specific thing in a program or a piece of code that represents that object.

What is a Face Recognition Attendance System?

Facial recognition is software that thoroughly maps a person’s facial attributes and stores them in the database to be used as a reference whenever they need the recognition. To validate an individual’s identification, the software compares a live capture or digital image to a piece of saved facial information using deep learning techniques.

The method of recognizing or verifying a person’s facial features is known as facial recognition. It uses a person’s facial characteristics to capture, analyze, and compare patterns. Face detection is required to detect and locate human faces in photos and videos. This detection has several advantages, including improved security, ease of integration, and automatic identification.

Facial recognition systems are used to track or identify people with criminal records who are wanted. When a database matches a person’s face, the developed algorithms make it easy to track down criminals. If the technology detects a facial match, the authorized personnel were notified.

UML Class Diagram for Face Recognition Attendance System

The UML class diagram is similar to a flowchart in which classes are represented by boxes with three rows inside. The top rectangle holds the class’s name; the middle rectangle contains the class’s properties, and the bottom row contains the class’s operation (methods). 

The class diagram is one of the most useful forms of UML diagrams because it elaborates the system’s structure by representing its classes, characteristics, processes, and object relationships.

Face Recognition Attendance System Class Diagram

Here’s the constructed Face Recognition Attendance System Class Diagram. It was provided with its attributes with matching methods to show the structure of each class. This is constructed with the simple idea derived from the common function of a Face Recognition Attendance System.

The illustration of a class diagram informs the project proponents on what are the characteristic (structure) of the software by showing the classes that will be included in the project. It resembles a chart in which classes are represented as boxes with three rectangles inside each box. The top rectangle has the class’s name; the middle rectangle contains the class’s properties; and the bottom rectangle contains the class’s methods, commonly known as operations.

UML Class Diagram for Face Recognition Attendance System (Explanation)

As you can see through the illustration, the classes were determined which is symbolized by boxes. They were designated with their corresponding attributes and shows the class’ methods. Their relationships are also plotted to show the connections between classes and their multiplicity.

You should also look into the visibility symbols displayed in the diagram. These are important because it declares the status of attributes in your Class Diagram. Some of the Class’ attributes are for public (+) which means that they can be accessed by the classes connected to them. While the protected (#) symbols, means that the attributes of the data can be accessed by the same classes or subclass and the (-) symbol means it cannot be accessed by other class.

Just bear in mind that when you create your class diagram, you have to be specific. Because it will affect your project development. Do not worry because you can use the sample given as your project reference or you may also create your own.

Steps in Developing Class Diagram

Time needed: 10 minutes.

Here are the complete steps in creating the class diagram for face recognition system

  • Step 1: Identify the classes of the system

    The first step is to determine the system’s included classes. A class (or classes) is an object or group of objects with similar structure and behavior. A rectangle with rows of the class name, attributes, and operations is used to represent them.

    The class name appears in the upper row of the class. This section is always important, whether you’re talking about the classifier or an object. The attributes of the class are located in the center section. Use this section to define the attributes of the class. This is only required when supplying a specific instance of a class.

    The operations of classes are listed in the bottom row (methods). In the list format, each operation gets its line. The methods by which a class interacts with data are known as operations.

  • Step 2: Know the classes’ connections (relationship)

    The next step is to figure out how each of the classes or objects is connected. When making the class diagram, look for similarities and differences between them to help you put them into groups. A relationship is a link between model components.

    This UML relationship is a model element that defines the structure and behavior between model elements, adding semantics to the model. To construct variations of these relationships, you can utilize attributes and keywords.

  • Finalize the structure of the Class Diagram

    The final step that you would do to finish your class diagram is to review the structure and finalize every class involved. Your class attributes and methods should be defined properly because they will be the guide for the project programming.

    Just remember that a class diagram is a form of a static structure diagram that depicts the structure of a system by displaying the system’s classes, attributes, operations (or methods), and relationships among objects.


The Face Recognition Attendance System Class Diagram is a modeled diagram that explains its classes and relationships. The diagram depicts the names and attributes of the classes, as well as their links and, their methods. It is the most essential type of UML diagram which is critical in software development. It is an approach to showing the system’s structure in detail, including its properties and operations.

The Face Recognition Attendance System must have a designed diagram to define the classes needed for the desired outcome. It is used to model the items that make up the system, depict their relationships, and define what those objects perform and the services they provide.
