AI in Emotion Recognition: How Does It Work?

Artificial intelligence-based emotion recognition technology is developing with speed, and the growing use of these technologies leads to the need for emotion recognition technologies in different sectors. The technologies, which have the potential to be used very effectively to improve services and increase customer satisfaction in different sectors, are also on the agenda with the expected increased use in areas such as security and medicine.

These developments force us to ponder a vital question: "How do you use emotion diagnostic technologies for your own work?" When you want to use this new technology for your business, you first need to understand what it is and how it works. In this article, you will find answers to your questions like:

· What is emotion recognition?

· How does emotion recognition work?

· Which platforms can I use for emotion recognition?

What is Emotion Recognition Artificial Intelligence?

AI-based emotion recognition is one of the fastest-growing areas of artificial intelligence and computer vision technologies. Based on face recognition technology, emotion recognition technology is a very complex task for the systems. Although it is a complex process, emotion recognition symbolizes a crucial building block in human-machine interaction.

The technology is based on the process of machine recognition and interpretation of human non-verbal cues. Facial gestures, facial expressions, eyebrow movements, etc., are the main factors required for machines to recognize emotions. The process is based on machines' analysis and classification of facial movements.

How Do Emotion Recognition Algorithms Work?

Emotion recognition is a very high-level task, and advanced artificial intelligence algorithms can do it. Emotion recognition technologies have improved rapidly in recent years with the development and improvement of deep learning algorithms and the Convolutional Neural Networks (CNNs) method. Deep learning models that work just like a human brain and can learn on their own from data are the foundation of emotion recognition technologies. Emotion identification is achieved through specific processes, which can be summarized as generating algorithms and processing data. Let's examine how emotion recognition works!

· Step I: Face Detection

Face detection is the first step in emotion recognition technology. First, human faces in images and/or videos are detected by artificial intelligence. Detection usually means framing the faces and identifying all human faces in the image. If you want to learn more about face detection technology, you can read our blog post on the subject by clicking here.

· Step II: Image Preprocessing

This is a crucial step. The faces detected in the previous step are used in this step. The quality of the images is improved, and the algorithm is fed with these improved face images.

· Step III: Emotion Classification AI

The faces detected in the first two steps are classified in this step. This step is undoubtedly the most complex step in the process and requires the most sophisticated algorithms. This step can use different algorithms, but CNN algorithms are the most commonly used.

This step is the classification of the characteristics of the selected faces. The faces in the data feeding the algorithm are classified in this step. As a result of the classification, we get images with specific labels. For example, "sad" or "happy."

For accurate emotion recognition, algorithms must be fed with large datasets. Although it is possible to find data sets created to provide these algorithms on the internet, this is challenging and time-consuming because algorithms need huge datasets.

While AI algorithms cannot detect every emotion that exists, they can detect most emotions that can be recognized from human facial expressions. While these recognition skills vary depending on the data, the algorithm is trained with, some basic emotions are recognizable for most algorithms. Let's see which emotions AI can recognize:

· Happiness

· Sadness

· Fear

· Disgust

· Anger

· Suprise

· Neutral

Usage Areas of Emotion Recognition?

Emotion recognition technologies have become prominent in many different fields. This is because the technology offers unprecedented service development opportunities, and in this part of our article, we will examine in which areas emotion recognition is used.

Education: This technology, which first became widespread during the pandemic, quickly became popular. The technology allows teachers to deal with children more accurately by analyzing emotions from students' facial movements during online education.

Medicine: AI-based emotion recognition software can help doctors diagnose neurological disorders such as depression or dementia more easily.

Recruiting: Emotion recognition software is already used to measure a candidate's credibility during job interviews!

Automated car Technologies: Automatedvehicles already use emotion recognition technologies, which is a highly advanced technology. These technologies measure the instantaneous state of the driver, allowing any accident to be avoided.

Insurance: Insurance companies are using emotion recognition technology to prevent insurance fraud.

Emotion recognition technologies are used in many other areas. Sectors such as video games, job security, border security, patient care, and banking are among the industries that have realized the importance of emotion recognition technology. It is thought that emotion recognition will be essential in the future of banking. It is even possible that banks will be alerted by emotion recognition from the cameras on ATMs, and offers will be made according to the instant mood of the customer.

Solution for Emotion Recognition on No-Code AI

As we mentioned throughout the article, emotion recognition is a very complex technology and can be done with highly sophisticated algorithms. Therefore, in order to use emotion recognition, you need to know very good coding and artificial intelligence technology. This means trained personnel, high costs, and a long operation time.

If you are not a very good software developer or do not have trained staff in this field, and if you are short on time and budget, you may find it difficult to start using this technology even though you need it. However, there is a solution:no-code platforms!

No-code platforms are ready to be the bridge between you and AI technologies with their user-friendly interfaces and fast processes. You can find the platforms you can use for emotion recognition in this section of our article.

There are a few no-code software available. For example, Face++ is software that you need to download to your computer while you can easily make applications such as face detection. In addition, the high operation cost also reduces the application's preferability.

Azur Face API, developed by Microsoft, is one of the software you can choose. Nevertheless, the slow development of the software is the main problem for many users.

AmazonRekognition is also one of the platforms you can use for diagnostics, but it is not that simple to use.

Cameralyze is a web-based, low-cost, easy-to-use platform for emotion recognition and much more. The platform stands out with its user-friendly interface and stands out from other competitors.
