Control of online evaluations online modality using artificial vision is a qualitative study that is based on the method of analysis and bibliographic conceptualization of 59 scientific articles taken from a total of 123 existing in the various bibliographic databases. The study began by addressing the issues concerned from the importance and understanding of online assessment control in the academic context to the types of computer vision algorithms and the main applications. To achieve this,

What techniques have been used to detect plagiarism in online evaluations? What machine vision algorithms are used? What are the main detection and monitoring tasks that computer vision algorithms are capable of performing? The research questions allowed us to investigate problems of academic dishonesty, ease of committing plagiarism, online assessment control techniques, plagiarism detection techniques, object tracking algorithms, region-based algorithms, grid-based algorithms, face detection, detection of gestures and object detection. To determine the most relevant articles, three phases were considered. Phase one took into account inclusion criteria such as scientific articles, reviews, conferences evaluated by peers, studies carried out on the artificial vision algorithm, as well as online evaluations. The second phase gave the word search chain greater relevance to the bibliographic review and to provide it with adequate capacity to answer the four research questions, was ordered by year of publication, the topic, abstract and keywords were reviewed. Phase three reviewed by sections corresponding to the introduction and conclusion to know if the information contributes and if it is related to the research questions. The results of the information extracted from the scientific articles show that there is a need for supervision of students during online assessments, which can occur through computer vision algorithms, since there have been significant advances in these areas.
