Abstract

Examination cheating activities like whispering, head movements, hand movements, or hand contact are extensively involved, and the rectitude and worthiness of fair and unbiased examination are prohibited by such cheating activities. The aim of this research is to develop a model to supervise or control unethical activities in real-time examinations. Exam supervision is fallible due to limited human abilities and capacity to handle students in examination centers, and these errors can be reduced with the help of the Automatic Invigilation System. This work presents an automated system for exams invigilation using deep learning approaches i.e., Faster Regional Convolution Neural Network (RCNN). Faster RCNN is an object detection algorithm that is implemented to detect the suspicious activities of students during examinations based on their head movements, and for student identification, MTCNN (Multi-task Cascaded Convolutional Neural Networks) is used for face detection and recognition. The training accuracy of the proposed model is 99.5% and the testing accuracy is 98.5%. The model is fully efficient in detecting and monitoring more than 100 students in one frame during examinations. Different real-time scenarios are considered to evaluate the performance of the Automatic Invigilation System. The proposed invigilation model can be implemented in colleges, universities, and schools to detect and monitor student suspicious activities. Hopefully, through the implementation of the proposed invigilation system, we can prevent and solve the problem of cheating because it is unethical.

摘要

考试作弊行为,如窃窃私语、头部动作、手部动作或手部接触等,广泛存在,这些作弊行为违反了公正、公平考试的原则和价值。本研究旨在开发一种实时监督或控制考试中不道德行为的模型。由于监考人员在考试中心处理学生的能力和能力有限,考试监督存在缺陷,而自动监考系统可以帮助减少这些错误。本工作提出了一种使用深度学习方法(即快速区域卷积神经网络(RCNN))进行考试监考的自动化系统。快速 RCNN 是一种目标检测算法,用于根据学生的头部运动检测考试过程中的可疑行为,并使用 MTCNN(多任务级联卷积神经网络)进行面部检测和识别,以识别学生。所提出模型的训练精度为 99.5%,测试精度为 98.5%。该模型在考试期间可以在一帧中高效检测和监控 100 多名学生。考虑了不同的实时场景来评估自动监考系统的性能。该监考模型可在学院、大学和学校实施,以检测和监控学生的可疑行为。希望通过实施拟议的监考系统,可以防止和解决作弊问题,因为作弊是不道德的。
