Accurate Face Detection and Recognition for High Performance 

As the brain is capable of conducting millions of highly complicated processes to execute high-quality pattern recognition tasks, most people have the ability to identify numerous objects automatically. This is because of automatic detection and recognition. 

Several efficient face detection algorithms have been devised in recent decades to transcribe this detection ability to computers and to enable computers to imitate various pattern recognition activities carried out by the human brain in both limited and uncontrolled situations. 

While all these studies were being carried out, a long way was covered to reach the most accurate face detection and recognition. In this article, we will touch upon accurate face detection for high performance

Accurate Face Detection 

The suggested face analysis system is designed to operate in unrestricted situations and needs just one face detection stage, the output of which is placed into a face recognition stage. As a consequence, even in the most unfavorable settings, it is important to establish the most appropriate steps and needed alterations in order to get the desired face recognition results. 

Face Detection Methods 

Face detection algorithms have been extensively studied among autonomous object identification schemes because of their potential application in a variety of practical systems, including video surveillance, biometrics, and access control systems, among others. 

The face is a biometric human trait that shows very identical information about the person. As a result, in many applications such as face recognition, face image retrieval, facial tracking, video surveillance, and so on, precise face detection is the initial step. 

Two methods are used for facial detection to be analyzed to get the most accurate face detection for high performance: 

  • Handcrafted based-face detectors 
  • Deep neural network-based face detectors 

Handcrafted Face Detection Methods 

Since the early days of machine learning, various computer vision applications have made use of approaches that require human intervention in the face detection process. Over the last several years, a broad array of cutting-edge algorithms for face detection have been created. 

These algorithms are now considered to be state-of-the-art. Finding the optimal balance between accuracy and processing economy is a task that often arises in the process of designing handmade features. 

In face detection and segmentation, the VJ algorithm has been shown to have excellent performance. Finding patterns in an area of interest can be accomplished by using texture-based descriptors such as the HOG and LBP. In their roles as face recognition algorithms, these two high-performance texture models deliver outstanding results. 

Deep Neural Network Face Detection Methods 

Neural networks have only very recently become a viable solution for the face detection challenge. As CNN employs deep learning methodologies, which are suitable for image and video processing, it has been shown in several studies that the features learned using deep neural networks give, in most circumstances, a superior generalization to the handcrafted features. 

Therefore, many effective systems that have been created in recent years have used deep neural networks for the purpose of face detection. The techniques for face recognition that are powered by deep neural networks can be broken down into two different categories: 

One-stage approaches: 

These systems predict classes and anchor boxes directly using a single feed-forward convolutional network design, eliminating the need for a second stage for the proposed operation. By retrieving, processing, and immediately categorizing and regressing the candidate anchor boxes, this method eliminates the candidate windows. 

Despite the fact that this form of algorithm is new, it has the potential to solve the speed issue. The first one-stage detectors entrenched in CNN are YOLO and SSD. Even though the accuracy of two-stage models, many of them are too sluggish to be used in real-time applications. As a result, for real-time face recognition, one-stage approaches are much more efficient. 

Face detection is divided into two phases by these schemes: 

➢ acquiring candidate windows 

➢ classifying and regressing the candidate windows 

These systems employ a Region Proposal Network to produce areas of interest in the first stage and then communicate the region proposals throughout the process for object categorization and bounding box regression in the second stage. 

Methods based on this technique often have a greater accuracy rate. R-CNN collections, such as fast R-CNN, Faster R-CNN, and R-FCN, are the most typical two-stage face detectors. 

So, besides this technical information, how accurate is face detection technology under real-world conditions? 

How accurate are face detection and face recognition technologies? 

Under perfect circumstances, when there is consistency in lighting and location, and if the facial characteristics of the subjects are clear and unobscured, accuracy scores of 99.97 percent are conceivable. This is the highest level of accuracy that can be achieved. 

When put under certain circumstances, the accuracy scores achieved by face detection are equivalent to the greatest results achieved by scanners. The problem is that it is difficult to meet such criteria in real-world situations. 

There are some factors affecting the accuracy of face detection so that facial recognition as well (we mentioned that facial detection is the initial step of face recognition or any other facial analysis). Here are these factors below: 


The natural process of aging has a significant bearing on the degree of precision that can be achieved by face recognition systems. The cheek highlights alter as a result of the variations in skin texture. 

Even though the most advanced algorithms are able to achieve impressive results regardless of the subjects' ages, a person's face can become less recognizable to a facial recognition system as they age due to changes such as wrinkles and shifts in facial shape. This is especially true for the elderly among us. 

Face Covers 

The use of a surgical mask, sunglasses, eyeglasses, earrings, and scarves are all examples of facial accessories that might result in a partial covering of the face. It is also possible for it to form as a result of hair, a mustache, or a beard. 

The accuracy of any face recognition algorithm is negatively impacted when covers are used. However, Cameralyze has already developed a facial recognition system that can identify individuals even while they are using masks. This is an adaptation to the new normal in which concealing one's face has become an essential method of preventing the transmission of the coronavirus. 

Poor image quality 

Images with a low resolution are often the product of surveillance cameras. The people who are seen in these kinds of photographs are often an essential component of an inquiry; nevertheless, it might be difficult to recognize them in comparison to a high-resolution database. 

Poor resolution can have a detrimental effect on the accuracy rates of measurement. Cameralyze employs point extraction in order to achieve reliable face recognition in a video image. 

This technology enables enhanced face recognition accuracy to the point where an individual can be identified with high precision from within a group, even if their face is partially hidden or the image is taken from different angles. 

This is possible even if the image is taken from different angles. Cameralyze face recognition system makes use of deep learning technologies for face matching as well. 

These technologies help boost accuracy to the point where a person's identity can be determined from a low-resolution face picture that was taken by a camera located far away. 


The way that light and shadow fall on the face of a person always has an effect on how they seem. As a result, photographs captured under a variety of lighting circumstances provide a possible obstacle for a face recognition system. 

Even while newer algorithms are more prone to mistakes as a consequence of light distortion, there are techniques to mitigate its impact and get reliable face recognition results.
