Special Issue Information

Dear Colleagues,

Recent years have seen significant improvements in information technology, such as 5G and high-speed web, which have led to the introduction of an advanced form of education using artificial intelligence (AI). While advanced education has been of interest to the research community for a while, the way the COVID-19 pandemic swept across the world, halting traditional education, led to increased attention on advanced education.

As is well known, new trends in education require novel technologies. Computer vision (CV) is a hotspot research domain in AI and one of the research directions closest to industrialization, so its application in advanced education is an important research domain for both the fields of AI and education.

The application prospects of computer vision in education are very promising; however, there is a number of challenges associated with this endeavor, which require much time and energy to solve. For example, automatic evaluation of objective tests needs handwriting recognition, and evaluation of subjective tests needs semantic understanding of the answer. Additionally, computer vision can be used to recognize the expressions and actions of students, which can infer students’ participation in the education. Moreover, computer vision can be used in educational technology, allowing students to more readily acquire knowledge and making abstract knowledge more intuitive.

Indeed, more effective applications are needed to solve the issues present in this area, and this Special Issue aims to provide an opportunity for researchers to publish their theoretical and technological studies on emerging theories in computer-vision-based intelligent education and their novel engineering applications within this domain. Surveys are also welcome.

In 21st-century society, with the rapid development of information technology, the scientific and technological strength of all walks of life is increasing, and the field of education has also begun to introduce high and new technologies gradually. Affected by the epidemic, online teaching has been implemented all over the country, forming an education model of “dual integration” of online and offline teaching. However, the disadvantages of online teaching are also very obvious; that is, teachers cannot understand the students’ listening status in real-time. Therefore, our study adopts automatic face detection and expression recognition based on a deep learning framework and other related technologies to solve this problem, and it designs an analysis system of students’ class concentration based on expression recognition. The students’ class concentration analysis system can help teachers detect students’ class concentration and improve the efficiency of class evaluation. In this system, OpenCV is used to call the camera to collect the students’ listening status in real-time, and the MTCNN algorithm is used to detect the face of the video to frame the location of the student’s face image. Finally, the obtained face image is used for real-time expression recognition by using the VGG16 network added with ECANet, and the students’ emotions in class are obtained. The experimental results show that the method in our study can more accurately identify students’ emotions in class and carry out a teaching effect evaluation, which has certain application value in intelligent education fields, such as the smart classroom and distance learning. For example, a teaching evaluation module can be added to the teaching software, and teachers can know the listening emotions of each student in class while lecturing. Full article
