Face recognition is one of the thriving technologies which effectively analysis images and videos to recognize faces. It is presented in every technology to identify the users in order to ensure the correct access to the intended accounts. Smart mobile phones are the greatest example of face recognition. The former decade’s researches have significantly contributed their part to developing face-recognizing techniques. “In this article, we have clearly stated about the things to be considered before writing a face recognition thesis”
In the earlier stages, techniques such as pattern recognition & computer vision are tried their best to offer consistent face recognition results by detecting and tracking the faces. In fact, now systems are developed well to perform all the required processes regarding face recognition. As the digital world is subject to security and privacy matters, it is demanding identity recognitions hence face-recognizing systems contributing their superlative features.
At the end of this article, you can able to write your own face recognition thesis. In point of fact, feature extraction is one of the important procedures of face recognition. In other words, it is the process of extracting the necessary data from a given image or video. These data can be used for the identification or verification processes of the subjects with reduced error rates.
Further, Evaluating time/duration & memory consumptions are determining the efficiency of the face recognition processes. In addition, outcomes of the face recognition are dealt with the optimization for the further classification phases. Now we can have the section about how the face recognition procedure works in real-time with clear handy notes.
How Face Recognition Works?
The face recognition system takes input in the form of image or video frames and verifies or identifies the subjects presented in the inputs. For your better understanding, we have vibrantly itemized the steps that are commonly used to recognize the faces of human beings.
- Face Recognition Inputs
- Face (Points) Detection
- Facial Feature Extraction
- Face Recognition
- Facial Emotion Recognition
The aforesaid are the major steps involved in recognizing the human faces besides there are several approaches that are often used to achieve the predetermined aspects. In that, some of the significant approaches practiced in every step are mentioned for making your understanding as strong.

The final stage of face recognition can be done with the help of above listed other steps. In the point of fact, verification (authentication) & identification processes are pillared by these steps. There is a database that is stored with a massive amount of images regarding human faces.
If an image or video is given into the face recognition processes, the system will perform the one-to-many matching and will get the identity report from the database. On the other hand, the identification process is done even if the input is unknown (unidentified), the system would match the individuals with the known individuals (identified) presented in that database.
In addition, the verification process is performed according to the one-to-one face matching tasks. Here the unknown users are authenticated by the identity claims. This is how face recognition works in general. Moreover, it is also vital to consider the accuracy of the face-recognizing systems. Reach us for more interesting face recognition thesis topics. Here, one of the major factors is illustrated that is affecting the face recognition accuracy levels for your better understanding.
Factors Affecting Face Recognition Accuracy
The accuracy of face recognition highly depends upon the selection of the FRT (Face Recognition Technology) techniques/algorithms. Those algorithms are explained below.
- Feature-based Face Recognition Algorithms
- Focuses on the facial features like eyes, nose & mouth, etc.
- Appearance-based Face Recognition Algorithms
- Appearance algorithms never consider the facial feature reflection & postures
- Hybrid Face Recognition Algorithms
- Hybrid is the combination of feature & appearance Face Recognition algorithms
- It is intended and proposed to diminish the false rates in recognition
In short, the selection of the Face Recognition algorithm is very important to achieve the great accuracy levels of face recognition. If you are trying your researches in face recognition areas consider handpicking the Face Recognition techniques. If it is failed there might be a lot of chances to face issues. In this regard, let’s discuss the key issues that are presented in the face recognition systems in general for your better understanding.

In point of fact, facial recognition is a little complex in nature because in recent days high-resolution cameras are having the capacity to renovate the facial feature with the help of their inbuilt features. In addition to that quality of the face, recognition falls under a question mark. In the subsequent passage, we have mentioned to you how we can enhance the facial recognition processes.
How Can Facial Recognition be improved?
Facial recognition processes can be improved according to the quality of images/videos acquired. The quality of the images is manipulated by the factors such as illumination (lighting), occlusion (obstruction) & postures/gestures of the individuals. In fact, these can be achieved with the application of several approaches as mentioned in the upcoming section.

How to Estimate the Performance of Face Recognition?
- ‘Yes’ and ‘no’ are the two binary decisions in facial verification processes
- ‘Yes’ signifies similar individuals & ‘no’ signifies the different individuals
- Errors categorization are done in the verification processes
- These two binary decisions always give the output in the 4 aspects as,
- False-negative: Identification of a single individual in 2 unlike persons
- False-positive: Shows the 2 dissimilar persons by way of the same person
- True negative: Exactly identifies the 2 dissimilar persons in given images
- True positive: Identification of identical person is given 2 images
